Abstract :

Copper-halide clusters emerge as a promising category of photoluminescent materials, attributed to their rich structural and photophysical properties in solid states. However, their environment-dependent emission quenching and challenges in film formation pose obstacles to their application in electroluminescent (EL) devices. Herein, we present Cu4Br4(AcNP)(2), a sublimable copper-halide cluster chelated by a bidentate N<^>P ligand with a donor-acceptor configuration. The steric and electronic modification effects of the dimethylacridine group not only induce predominant (metal + halide)-to-ligand charge transfer and intra-ligand charge transfer characters in the excited states of the cluster, ensuring efficient and short-lived thermally activated delayed fluorescence, but also effectively prevent concentration quenching in films by avoiding intermolecular pi-pi stacking. As a consequence, 40 wt% doped and non-doped devices achieve maximum external quantum efficiencies of 12.8% and 10.2%, respectively. We anticipate that the current study offers insights into the design of copper-halide clusters for fabricating highly efficient EL devices, especially for non-doped EL devices.

共价有机框架双电场叠加实现高效光催化产氢

Abstract :

光催化水分解制氢是解决环境污染和能源危机的理想途径.共价有机骨架(COFs)作为一类由共价键连接的周期性网状拓扑材料,其电子结构和化学性质可在分子水平上进行定制和调控,是研究半导体光催化剂构-效关系的理想模型.为了提高COFs的电荷分离效率,在COFs骨架上设计供体-受体(D-A)单元,构筑分子内电场(IMEF)促进电荷定向迁移是一种行之有效的策略.然而,在亚胺键连接的COFs中,亚胺键取向诱导产生的键内电场(IBEF)对光生激子的分离效率的影响往往被忽视.因此,进一步研究IMEF与IBEF之间的相互作用对COFs内光生电子转移动力学的影响具有重要意义,可为深入揭示光催化产氢机制提供关键信息. 本文报道了一种基于COFs的双电场叠加策略,用于提高光催化产氢反应效率.首先,通过将有机单元的末端官能团进行互换,利用水热法成功制备了两种亚胺键取向相反的强D-A型COFs光催化剂,TNCA和TCNA.其中,官能团的微小变化保证了由D-A结构组成的IMEF方向和强度的一致性,可以使得在仅改变IBEF的情况下全面研究COFs的电子结构.X射线粉末衍射、傅里叶变换红外光谱、固体核磁以及X射线光电子能谱等结果证实了两种COFs的成功合成.随后,扫描电镜、透射电镜和氮气等温吸脱附曲线结果表明两种COFs均为介孔材料.紫外-可见漫反射光谱结果表明,所制备的催化剂具有良好的可见光吸收能力,结合莫特肖特基曲线结果,表明催化剂在热力学上均满足光催化产氢的要求.采用光致发光光谱、时间分辨荧光光谱、电子顺磁共振、光电流以及电化学阻抗研究了两种催化剂的载流子分离和转移行为,并且利用飞秒瞬态吸收光谱进一步明确了COFs中光生电荷转移动力学过程.结果表明,相较于TCNA,TNCA在光照下能够产生更多的光生电子且具有更长的寿命.光催化产氢活性评价结果显示,在可见光(A ≥ 420nm)照射下,具有同向叠加电场的TNCA,光催化析氢速率高达57.3 mmol·g-1·h-1,是具有相反电场取向TCNA(0.11 mmol·g-1·h-1)的520倍.并且TNCA具有更负的导带能级,有利于光生电子参与还原过程,最终获得较好的光催化析氢性能.此外,理论计算结果表明,当IMEF和IBEF取向一致时,亚胺键不仅可以为载流子迁移提供强大的驱动力,而且还能够有效地抑制载流子复合,进一步提高光生电子的利用率. 综上所述,本文提出了双电场叠加增强光生载流子高效分离的有效策略,为设计具有特定电场性质的COFs光催化材料提供了理论及实际参考.

Abstract :

Precise and efficient management of disulfide bonds will offer multiple merits for the development of organosulfur chemistry, pharmacology, and life sciences. However, the current S-S coupling synthesis strategy encounters bottlenecks in conforming to efficient separation of products, which limits its industrial-scale application. In view of the superoxide radical-triggered reaction mechanism of S-S coupling, this study demonstrates a multifunctional in situ-assembled 0D/1D S-scheme heterojunction photocatalyst (MAPB-T-COF) constructed by MAPbBr(3) quantum dots and imine covalent organic framework (COF) nanowires under the guidance of band engineering management. MAPB-T-COF exhibits a superior photocatalytic performance in the conversion of 4-methylbenzenethiol (4-MBT) to p-tolyl disulfide (PTD) under blue LED illumination. Specifically, it achieves an impressive 100% yield with a record photon quantum efficiency as high as 12.76%, as well as universal availability for various derivatives, rivaling all the incumbent similar reaction systems. This study not only highlights the effectiveness and merits of nanoscale S-scheme heterojunction photocatalysis for the S-S coupling reaction but also achieves a perfect trade-off between high quantum efficiencies and strong chemical redox potentials. In addition, the free radical that triggers the reaction was monitored in situ by an electron paramagnetic resonance (EPR) instrument, which provided meaningful insights into the reaction mechanism. This study may inspire the development of photoelectric conversion devices, photoelectrodes, and photocatalysts utilizing nanoscale, low-dimensional heterojunctions.

Abstract :

The increasing dangerous chemical pollutants led by shipping accidents call for the new pollutant treatment strategy. In this work, a new three-component hybrid {[(BiI6)I-13]center dot 2I(3)center dot(H-BPA)(4)}(n) (1) can be used in dye degradation in seawater. The highly interesting feature of 1 lies in its unique 1-D Z-shape [(BiI6)I-13](n)(6-) infinite chain constructed from the I center dot center dot center dot I contacts between mono-nuclear (BiI6)(3-) anions and I-13(3-) polyiodide anions. Finally, the hydrogen bonds between [(BiI6)I-13](n)(6-) polyanions and H-BPA(2+) cations contribute to the formation a quasi-3-D network. Specifically, 1 exhibits the wide absorption zone from ultraviolet to visible regions and high charge-separation efficiency, hinting its application in visible-light catalysis. As expected, 1 represents photocatalytic activity for the degradation of rhodamine B in seawater with degradation ratio of 90%, and the photocatalytic performance is stable. This work might provide new photocatalytic material for pollutant treatment in shipping accidents.

Abstract :

Two copper(I) iodide tetramers, namely, [mu(2)-1,3-bis(diphenylphosphanyl)pro-pane-kappa P-2:P']di-mu(3)-iodido-di-mu(2)-iodido- [1- (pyridin-3-yl)ethan-1-one-kappa N] tetracopper (I) dichlorome thane disolv ate, [Cu4I4(C6H7NO)(2)(C27H26P2)(2)]center dot 2CH(2)Cl(2) (CuL3), and [mu(2)-1,3-bis(diphenylphosphanyl)propane-kappa P-2:P']di-mu(3)-iodido-di-mu(2)-iodido-[1-(pyridin-4-yl)ethan-1-one-kappa N]tetracopper(I), [Cu4I4(C6H7NO)(2)(C24I26P2)(2)] (CuL4), have been synthesized from reactions of CuI, 1,3-bis(diphenylphosphanyl)propane (dppp) and 3- or 4-acetylpyridine (3/4-acepy). The complexes were characterized by elemental analysis, IR spectroscopy, singlecrystal X-ray diffraction (XRD), powder XRD and photoluminescence spectroscopy. Both complexes possess a stair-step [Cu4I4] cluster structure with a crystallographic inversion centre located in the middle of a Cu2I2 ring (Z' =1/2). The dppp ligands each adopt a bidentate coordination mode that bridges two Cu' centres on one side of the [Cu4I4] cluster and the acepy ligands act as terminal ligands. The solid-state samples of similar complexes show highly efficiency thermally activated delayed fluorescence (TADF) at room temperature. At ambient temperature, both CuL3 and CuL4 exhibit photoluminescence, with a maximum emission in the region 560-580 nm and with short emissive decay times, but only phosphorescence was observed at 77 K. The narrow gaps between the higher lying singlet state and the triplet state, Delta E(S-1-T-1), also confirm the presence of TADF. Structure analysis and consideration of photoluminescence indicates that the position of the acetyl group on the heterocyclic ligand has an obvious influence on the structural arrangement, on intermolecular interactions and on the observed photophysical properties.

Abstract :

Treatment of bis(diphenylphosphino)methane (dppm) and 2-(diphenylphosphanyl)pyridine (dpppy) with Cu(CH3CN)(4)BF4 afforded a dinuclear Cu(I) complex [Cu-2(dpppy)(2)(dppm)(CH3CN)](BF4)(2)center dot 3CH(2)Cl(2) (1). Complex 1 was structurally characterized by X-ray single-crystal analysis and its photophysical properties were studied in detail. It crystallizes in triclinic space group P (1) over bar with a = 13.0834(8), b = 13.5568(8), c = 21.8544(11) angstrom, alpha = 76.090(5)degrees, beta = 80.803(5)degrees, gamma = 64.582(6)degrees, V = 3391.3(3) angstrom(3), Z = 2, M-r = 1507.42, D-c = 1.476 g/cm(3), F(000) = 1532, GOOF = 1.071, the final R = 0.0700 for 9041 observed reflections with I > 2 sigma(I) and wR = 0.2063 for all data. The complex contains a Cu-2-core structure surrounded by one dppm and two dpppy ligands in a head-to-head arrangement. In the crystalline phase, complex 1 exhibits bright bluish-green photoluminescence (lambda(max) = 488 nm) with high quantum yield (phi = 0.57) at room temperature. It is still a relatively high emission quantum yield (phi = 0.36) in doped PMMA thin film with 20 wt% dopant of complex 1. The emission peaks of 1 in dichloromethane solution and doped PMMA (20 wt%) thin films are 510 and 494 nm, respectively, showing a very slight bathochromic shift compared to that in crystalline phase. This phenomenon might be attributed to its rigid conformation that precludes the possible distortion of copper centers in the excited state.

Abstract :

A novel stilbene-based salicylhydrazone compound {systematic name: (E)-4,4'-(ethene-1,2-diyl)bis[(N'E)-N'-(2-hydroxybenzylidene)benzohydrazide] dimethyl sulfoxide disolvate, C30H24N4O4 center dot 2C(2)H(6)OS or L center dot 2DMSO} was synthesized and characterized by single-crystal X-ray diffraction, powder X-ray diffraction and luminescence spectroscopy. The title compound crystallizes in the monoclinic space group P2(1)/c, with half a symmetry-independent L molecule and one dimethyl sulfoxide (DMSO) solvent molecule in the asymmetric unit. The L molecule adopts an almost planar structure, with a small dihedral angle between the planes of the stilbene and salicylhydrazone groups. There are multiple pi-pi stacking interactions between adjacent L molecules. The DMSO solvent molecules act as proton donors and acceptors, forming hydrogen bonds of various strengths with the L molecules. In addition, the geometry optimization of a single molecule of L and its luminescence properties either in solution, as a solvated solid or as a desolvated solid were studied. The compound shows an aggregation-induced emission (AIE) effect and exhibits switchable luminescence colouration in the solid state by the simple removal or re-addition of the DMSO solvent.

Abstract :

When the chiral coordination polymers were composed of achiral molecules, the deracemization of the bulk product remains a great challenge if without any chiral induction. The Viedma ripening theory was adopted herein to help the achievement of mirror symmetry breaking for the bulk chirality of two chiral coordination polymers. The enantiomeric excess of the bulk chirality for the first compound is about 100%, which means absolute asymmetric synthesis. The deracemization degree of the bulk chirality for the second compound fluctuates occasionally. Further study has discussed the different deracemization degree of the bulk chirality for two compounds with the consideration of enantioselective incorporation in crystal cluster.

Abstract :

Naphthalenediimides, an attractive class of electron-deficient organic dyes with rich redox and photoredox properties, have been investigated extensively as building blocks for coordination networks or metal-organic frameworks in recent decades. However, most of the available work has focused on d-block metal cations rather than f-block lanthanide ions, whose complexes exhibit a large variability in coordination numbers. In this article, four coordination polymers composed of naphthalenediimides and lanthanide cations, namely catena-poly[[[tris(nitrato-kappa O-2,O')lanthanide]-bis{mu-N,N'-bis[(1-oxidopyridin-1-ium-3-yl)methyl]-1,8 4,5-naphthalenetetracarboxdiimide-kappa O-2:O'}-[tris(nitrato-kappa O-2,O')lanthanide]-mu-N,N'-bis[(1-oxidopyridin-1-ium-3-yl)methyl]-1,8:4,5-naphthalenetetracarboxdiimide-kappa O-2:O'] methanol disolvate], {[Ln(C26H16N4O4)(1.5)-(NO3)(3)]center dot CH3OH}(n), with Ln = Eu, 1, Gd, 2, Dy, 3, and Er, 4, have been successfully synthesized under hydrothermal conditions. Single-crystal X-ray diffraction analyses revealed that the four compounds are isomorphic and that each asymmetric unit contains one nine-coordinated Ln centre, one and a half diimide ligands, three nitrate anions and one uncoordinated methanol molecule. In addition, each metal centre is surrounded by nine O atoms in a distorted tricapped trigonal-prismatic geometry. Two centres are bridged by two cis ligands to form a ring, which is further bridged by trans ligands to generate one-dimensional chains. Neighbouring chains are stacked via pi-pi interactions between pyridine rings to give a two-dimensional structure, which is stabilized by pi-pi interactions between naphthalene rings, forming the final three-dimensional supermolecular network. Solid-state optical diffuse-reflectance spectral studies indicate that compound 4 is a potential wide band gap semiconductor.

Abstract :

Two lanthanide-organic frameworks [Ln(HPIDC)(m-bdc)center dot 1.5H(2)O](n) (Ln = Eu 1 or Tb 2; H3PIDC = 2-(4-pyridyl)-1H-imidazole-4,5-dicarboxylic acid; m-H(2)bdc = 1,3-benzenedicarboxylic acid) were synthesized under hydrothermal conditions. Compounds 1 and 2 are all of a 3D 6-connected pcu topology. There are uncoordinated nitrogen atoms in the molecule, indicating that the uncoordinated pyridine groups and imidazole groups can serve as functional groups. We tested their luminescence detection ability for cations and anions. Fluorescence measurements show that two compounds (1 and 2) can detect Cr2+ ions and Cr2O72- anions with high selectivity and sensitivity, which suggests that the two Ln-MOFs are promising functional luminescent sensor materials for sensing metal ions and anions.
