Fine-tuning metal–organic framework performances by spatially-differentiated postsynthetic modification
31次浏览
Hai-Feng Zhang, Mian Li, Xue-Zhi Wang, Dong Luo, Yi-Fang Zhao, Xiao-Ping Zhou,* and Dan Li*Abstract:In contrast to the regular postsynthetic modification (PSM) approach which is global and random in principle, a diffusion-controlled PSM strategy utilizing sizemismatch between pores and reactants has been developed to target selective functionalization and fine-tuning of material performance. Demonstrating through narrow-pore ZIF-90 reacting with amines of contrasting aliphatic chain lengths, we

Yun-Lei Peng, Jingyi Liu, Hai-Feng Zhang, Dong Luo and Dan Li *Abstract:A composite of Keggin-type phosphotungstic acid (H3PW12O40) encapsulated in sized-matched metal–organic framework UiO-67 (PW12@UiO-67) was prepared as a heterogeneous catalyst for extractive and catalytic oxidative desulfurization systems (ECODS). The appropriate cage size and narrow windows of UiO-67 serve to avoid the leaching of phosphotungstic acid, and also allow most sulfur compounds commonly found in fuels to approach

Robust heterometallic MOF catalysts for the cyanosilylation of aldehydes
34次浏览
Jia-Jia Du, Xiang Zhang, Xiao-Ping Zhou,* and Dan Li*Abstract:In this work, Zn2+ and Cu2+ ions are doped into a Mn2+ based frail MOF (STU-2) to form heterometallic MOFs. These metal doped MOFs show a good stability and heterogeneous catalytic activity for the cyanosilylation reactions of aromatic aldehydes. The catalysts can be reused at least for three cycles.文章链接:C8QI00811F.pdf

Chiroptical Activity from an Achiral Biological Metal−Organic Framework
35次浏览
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

Boosting Luminescence of Planar-Fluorophore-Tagged Metal–Organic Cages Via Weak Supramolecular Interactions
29次浏览
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

Self-Assembly of Chiral Metal−Organic Tetartoid
23次浏览
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
