Abstract ：
The optical performance of metal oxo clusters has attracted increasing research attention. Here, we investigate the photophysical properties of heterometallic Sn-Ti oxo clusters incorporating conjugated ligands. Three unprecedented dual-layered Sn-Ti oxo clusters were prepared using 1,10-phenanthroline as a functional ligand with formulas: [SnII2TiIV12(mu 3-O)6(mu 2-O)12(phen)8(Pr)10Cl2]center dot(SnIICl3)2 center dot(Pr)2 center dot(CH3CN)2 (TOC-61, HPr = propionic acid; phen = 1,10-phenanthroline), [SnII2TiIV12(mu 3-O)8(mu 2-O)10(phen)8(IPA)4(Pr)8Cl2]center dot(SnIICl3)2 (TOC-62, HIPA = isopropanol), and [SnII6TiIV14(mu 3-O)9(mu 2-O)14(phen)6(Pr)14Cl6]center dot SnIICl3 center dot Pr (TOC-63). The distances between the 1,10-phenanthroline ligands in the three structures are in the ranges of 3.636-4.139, 3.692-4.388 and 3.422-4.001 angstrom, respectively, so that they all have strong intramolecular pi MIDLINE HORIZONTAL ELLIPSIS pi interactions. Moreover, TOC-62 exhibits stronger intermolecular pi MIDLINE HORIZONTAL ELLIPSIS pi interactions than TOC-61 and TOC-63. The optical gap values of TOC-61 to TOC-63 are 2.04, 1.95 eV, and 2.27 eV, respectively. The open aperture (OA) Z-scan measurements show that the three compounds all exhibit an obvious third-order nonlinear optical (NLO) response, as well as laser irradiation stability and repeatability. Interestingly, with the enhancement of the pi MIDLINE HORIZONTAL ELLIPSIS pi interactions in these heterometallic Sn-Ti oxo clusters, the general trend of the optical gaps is gradually reduced and optical limiting (OL) effects are gradually enhanced. This work offers a route for preparing heterometallic Sn-Ti compounds with interesting optical properties, and provides a platform for studying the structure-performance relationship of heterometallic materials at the molecular level. Heterometallic Sn-Ti oxo clusters functionalized with conjugated 1,10-phenanthroline ligands have been prepared, which exhibit distinct optical bandgaps and optical limiting properties influenced by pi MIDLINE HORIZONTAL ELLIPSIS pi interactions.

Abstract ：
The development of new metal-organic frameworks (MOFs) thin films is important for expanding their functions and applications. Herein, we first report a new kind of MOF thin film by using aggregation-induced emission (AIE) dicarboxyl ligand through a liquid-phase epitaxial (LPE) layer-by-layer (LBL) spraying method (named AIE surface-coordinated metal-organic frameworks thin film, AIE-SURMOF). The obtained AIE-SURMOF Zn4O(TPE)3 (ZnTPE) has highly growth orientation and homogeneous thin film, showing strong fluorescent property. Furthermore, by loading chiral guest in the MOF pore, the formed chiral encapsulated AIE-SURMOF can clearly indicate obvious circularly polarized luminescence performance with glum of 0.01. This study provides new MOF thin film and new strategy for expanding function and application of MOF materials.

Abstract ：
Herein the chiral resolution of racemic Zr4L6 tetrahedral cages has been realized using luminescent enantiopure coordination cations. Accordingly, anionic ΔΔΔΔ-Zr4L6 and ΛΛΛΛ-Zr4L6 cages (L = embonate) were completely resolved using enantiopure [Ag(R-BINAP)2]+ and [Ag(S-BINAP)2]+ cations, respectively, and a pair of pure enantiomers (PTC-374(R,Δ) and PTC-374(S,Λ); PTC = polynuclear titanium cage) were easily prepared and structurally well-characterized, featuring an uncommon cage-supported supramolecular framework with zeolitic SOD topology. The stepwise transfer of homochirality can be clearly observed in the unusual resolution process. Moreover, the perfect combination of two functional components endows such co-assembled materials with synergistic circular dichroism performance, enhanced fluorescence and circularly polarized luminescence response. © 2024 The Royal Society of Chemistry

Abstract ：
In this work, we synthesized two Cu-based heterometal-oxo clusters 1 and 2 based on M(III)(4)O-4 (M = Fe/In) cubane centers and obtained the corresponding dimers 3 and 4 by connecting Cu atoms on the cluster cores with the auxiliary ligand 4,4 '- bipyridine. They were characterized by single-crystal X-ray diffraction (SCXRD), powder X-ray diffraction (PXRD), and other tests. We conducted magnetic property study on compounds 1-4. The variable-temperature magnetic susceptibility test shows that compounds 1 and 3 exhibit significant ferromagnetic interactions at low temperatures, while compounds 2 and 4 exhibit overall antiferromagnetic interactions. When the metal at the cubane changes from magnetic Fe to nonmagnetic In, the magnetic interactions in the compound are weakened to a certain extent. Through dimerization, the extreme values of the variable-temperature magnetic susceptibility appear (1 to 3)/disappear (2 to 4) in the low-temperature section. We investigated the magnetic structure correlation of compounds 1-4 through bond lengths, bond angles, and distances between magnetic atoms. The results showed that compounds 1-4 exhibited significant magnetic coupling diversity.

Abstract ：
Macrocyclic compounds are of great interest for their ability to capture guest molecules into their cavities. In particular, host-guest interaction plays a crucial role in the formation of supramolecular compounds. Herein, two host-guest supramolecular compounds, [Al-8(OH)(8)(L)(16)]2HL (HL@AlOC-166, HL = 4-Iodobenzoic acid) and [Al-8(OH)(8)(L)(8)(L-1)(8)]2DMF (DMF@AlOC-166, HL1 = isoamyl alcohol), are acquired by introducing different types of guest components based on the internal pore cavities of the aluminum molecular ring [Al-8(OH)(8)(L)(16)] (AlOC-166). The inclusion of these guests is attributed to the presence of abundant hydrophilic OH serving as the hydrogen bond donors inward the ring cavity. Host-guest compounds usually exhibit superior nonlinear optical (NLO) response due to the existence of guest molecules that could change symmetry, dipole moments, charge distributions, etc. Unexpectedly, the AlOC-166 achieved the best NLO results, although it had no guest molecules inside its molecular ring, which breaks the traditional concept. The reason for this trend can be explained by the difference in intermolecular force rather than intramolecular interaction, mainly related to the amount and strength of pipi and C-Ipi interactions in different compounds. This work investigates the effect of host-guest interaction on NLO, representing a new perspective for designing optical limiting materials.

Abstract ：
Different from the previous neutral reaction solvent system, this work explores the synthesis of Al-oxo rings in ionic environments. Deep eutectic solvents (DESs) formed by quaternary ammonium salts hydrogen bond acceptor (HBA) and phenols hydrogen bond donor (HBD) further reduce the melting point of the reaction system and provide an ionic environment. Further, the quaternary ammonium salt was chosen as the HBA because it contains a halogen anion that matches the size of the central cavity of the molecular ring. Based on this thought, five Al8 ion pair cocrystals were synthesized via “DES thermal”. The general formula is Q+ ⊂ {Cl@[Al8(BD)8(μ2-OH)4L12]} (AlOC-180-AlOC-185, Q+ = tetrabutylammonium, tetrapropylammonium, 1-butyl-3-methylimidazole; HBD = phenol, p-chlorophenol, p-fluorophenol; HL = benzoic acid, 1-naphthoic acid, 1-pyrenecarboxylic acid, anthracene-9-carboxylic acid). Structural studies reveal that the phenol-coordinated Al molecular ring and the quaternary ammonium ion pair form the cocrystal compounds. The halogen anions in the DES component are confined in the center of the molecular ring, and the quaternary ammonium cations are located in the organic shell. Such an adaptive cocrystal binding pattern is particularly evident in the structures coordinated with low-symmetry ligands such as naphthoic acid and pyrene acid. Finally, the optical behavior of these cocrystal compounds is understood from the analysis of crystal structure and theoretical calculation. © 2024 American Chemical Society.

Abstract ：
The integration of anionic Ti4L6 (L = embonate) cages and π-conjugated coordination cations into ordered structures can produce high-performance nonlinear optical (NLO) materials. More specifically, by employing Ti4L6 cages for assembly with mixed N,N-chelated and P,P-chelated type conjugated organic ligands and Ag+ ions, three cage-based structures have been synthesized and structurally characterized. Among them, an ion pair structure with strong π-π accumulation exhibits a significant third-order NLO response, and an excellent optical limiting effect has been experimentally verified. This work provides a promising material for NLO applications. © 2024 The Royal Society of Chemistry.

Abstract ：
Producing Cn products through electrocatalytic CO2 reduction reaction (CO2RR) is of great significance in addressing the global warming crisis. Organic-inorganic hybrid catalysts, characterized by precise and controllable active sites and metal-ligand synergistic interactions, can enhance the reaction activity and stability of Cubased catalysts. Herein, based on density functional theory (DFT), a novel flexible aromatic Cu3 metal-organic t-cluster (Cu3-t cluster) was constructed, consisting of triple-atom active centers and pentalyne ligands. During the catalytic CO2RR process, the adsorption of H can promote the activation of CO2, this converts the competing hydrogen evolution reaction (HER) into promoting CO2RR. Enhanced aromaticity of its cluster core is credited with stabilizing the coadsorption of H and CO2 (H* + CO2*), consequently lowering the reaction free energy of the CO2 activation process. Research has shown that Cu3-t cluster have high catalytic activity for electrocatalytic CO2 generation of C2H4. Considering the solvation effect, the limit potential of this reaction is -0.60 V. Furthermore, the reaction free energies suggest that the Cu3-t cluster is more inclined to yield C2H4(g) products via COCO* coupling. Moreover, the high CO coverage at the triple-atom active centers not only makes it more challenging for this cluster to adsorb H, but also reduces the energy barrier of the COCO* coupling reaction. In the entire reaction pathway of C2H4(g), there exhibits dynamic self-adaptive behavior in the bond lengths and bond angles of the three Cu atoms in the cluster core, leading to fluctuations in aromaticity. The flexibility and aromaticity changes in this structure enable the Cu3-t cluster to better stabilize intermediates. This work provides theoretical guidance for the application of metal-organic t-clusters, accelerates the screening of catalysts for CO2RR, and provides powerful theoretical guidance for the structure-activity relationships between aromaticity and catalytic activity.
