Li-Li Xu, Hai-Feng Zhang, Mian Li, Seik Weng Ng, Jiang-He Feng, Jiang-Gao Mao, and Dan Li*Abstract:Chiroptical activity is observed from an achiral adenine-containing metal−organic framework (MOF) named ZnFDCA. Such a seemingly counterintuitive phenomenon can, in fact, be predicted by the intrinsic crystal symmetry of 4̅2m point group. Although theoretically allowed, examples of optically active achiral crystals are extremely rare. ZnFDCA is the first reported achiral MOF showing optical activit

Dong Luo,⊥Mian Li,⊥Xiao-Ping Zhou,* and Dan Li*Abstract:A variety of planar organic fluorophores (R= phenyl, naphthalenyl, pyrenyl) and luminescence promotors(X=Cl, Br, I) were equipped, respectively, on the alternatively arranged vertices of cubic ZnII-imidazolate cages through orthogonal subcomponent self-assembly. It was found that supramolecular interactions, especially weak C@H···X interactions, play a key role in activating an efficient radiative pathway, coupled with reduced nonradiatived

Dong Luo,⊥Xue-Zhi Wang,⊥Chen Yang, Xiao-Ping Zhou,* and Dan Li*Abstract:Chiral coordination cages feature both chirality and defined inner space, providing advanced molecular materials. A series of chiral 20-nucleus cobaltimidazolate cages were synthesized by self-assembly of 72 subcomponents, featuring a novel tetartoid (tetragonal pentagonal dodecahedron) structure. Spontaneous resolution of racemic tetartoidal cages (Δ and Λ) into a conglomerate of homochiral crystals are observed, while both

Yun-Long Hou, Yunhong Pi, Xiao-Ping Zhou, and Dan Li*Abstract:Three coordination polymers (CPs) with square-planar CuII/NiIIN4 subunits were formed in one step by subcomponent self-assembly, giving rise to an unprecedented linking variety of in situ embedded metalloligands and CuI clusters. All CPs exhibit unusual visible-light adsorption. Enhanced photocatalytic activity and high selectivity were observed in the oxidation of benzene under visible-light irradiation.文章链接：acs.inorgchem.7b03068.pdf

Shun-Ze Zhan,* Xia Jiang, Ji Zheng, Xin-Da Huang, Guang-Hui Chen and Dan Li*Abstract:A highly luminescent supramolecular Cu2I2(NH3)2-sandwiched Cu3(pyrazolate)3 adduct was reported as a temperature sensor. The adduct is stabilized by the synergy of intermolecular Cu3⋯I (π acid⋯base), Cu⋯Cu and N⋯H interactions, to form a Cu8I2 cluster. The emission intensity exhibits a temperature-dependent effect in the solid state with a sensitivity of −0.685% K−1. DFT and TDDFT calculations revealed that the

自C60富勒烯分子被发现以来，以C60为代表的富勒烯及其衍生物，如外联金属富勒烯、内嵌金属富勒烯、有机富勒烯衍生物、富勒烯超分子、富勒烯掺杂功能材料等，一直是化学与材料科学的研究热点。相对于单纯的富勒烯分子，这些衍生物在光、电、磁等方面更具有优良的性质，在功能材料开发方面更具有广泛的应用前景。近日，继在通过超分子配位组装策略成功地制备出具有土星环状结构的C60-咪唑铜超分子化合物（Chem. Commun.,2020,56, 3325）之后，李丹教授研究团队在高核铜(I)富勒烯核壳结构配合物研究方面又取得了新的突破（J. Am. Chem. Soc.,2020,142, 5943）。C60分子球面具有30对非完全离域的p电子。从配位化学的角度来看，C60分子可以通过30个C=C以hapto方式与30个过渡金属原子M配位，形成截半二十面体(Icosidodecahedron)的三十二面体核壳结构C60@M30（图a）。然而，目前报道的结构中，C60最多只与6个M配位。主要原因可能是这些开壳层过渡金属都显示出较高的配位数，多个辅助配体引起的空间位阻不利于更多的金属原子在C60分子表面聚集配
