Abstract :
Although many racemic M4L6 cages have been synthesized, little attention has been paid to the resolution of M4L6 cages because resolution of these cages is very difficult. To explore the use of optically pure M4L6 cages in chiral applications, it is important to obtain a single enantiomer. In this work, the anionic ΔΔΔΔ-Zr4L6 and ΛΛΛΛ-Zr4L6 (L = embonate) cages have been completely separated by introducing chiral organic ligands R/S-BINAP and 1S,2S/1R,2R-DPEN, respectively, and the active vertex of homochiral Zr4L6 cage traps π-conjugated coordination silver cations (such as [Ag2(DPPM)2]2+, chiral [Ag2(PPh3)2(DPEN)]2+ and [Ag(PPh3)(DPEN)]+), obtaining two pair of pure enantiomers (PTC-375(Δ/Λ) and PTC-376(Δ/Λ)). Interestingly, the chiral resolution and surface modification of such zirconium cage endow it with homochirality and significant circularly polarized luminescence (CPL) response, and PTC-376 enantiomers show a CPL output with glum values up to ∼1.4 × 10−2. This work not only provides a new resolution strategy for metal-organic cages, but also expands their chiral application especially in CPL field. © 2025

Abstract :
Binaphthyl-based chiral organic molecules have attracted considerable attention due to their potential in circularly polarized luminescence (CPL). In this study, three pairs of enantiomerically pure binaphthyl derivatives (R/S-1, R/S-2, and R/S-3) were synthesized, and their optical properties were systematically investigated in both the amorphous and crystalline states. Notably, the crystalline forms exhibited significantly enhanced CPL activity compared to their amorphous counterparts, with R/S-3 showing a nearly 10-fold increase in |g lum|. Single-crystal X-ray diffraction analysis revealed that enhanced intermolecular interactions and highly ordered 21-helical packing promote efficient exciton migration and chiral amplification, accounting for the improved CPL performance. This work provides new insights into CPL enhancement via crystalline-state engineering and offers guidance for developing practical CPL-active materials.

Abstract :
Cerium metal-organic frameworks (Ce-MOFs) have attracted extensive attention due to their potential in photocatalytic applications. However, Ce-MOFs constructed with organic carboxylic acids as ligands typically exhibit wide band gaps, which limit their utilization in the visible-light region. This work proposes a strategy to design visible-light-active Ce-MOFs by employing quinoline sulfonic acid as a ligand. The synthesized compound (1-Ce) features a high surface area, open Ce metal sites, and large-sized 1D channels. Benefiting from ligand-to-metal charge transfer, 1-Ce demonstrates good visible light absorption. Additionally, the chelating coordination of nitrogen and oxygen atoms endows 1-Ce with excellent chemical stability. Owing to its abundant metal sites, high porosity, and visible light responsiveness, 1-Ce exhibits outstanding photocatalytic activity for CO2 reduction under visible light, achieving a CO production rate of 138 mu mol.g(-1).h(-1)-surpassing previously reported Ce-MOF photocatalysts.

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 :
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 :
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 Delta Delta Delta Delta-Zr4L6 and Lambda Lambda Lambda Lambda-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,Delta) and PTC-374(S,Lambda); 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.
