Ying Zhang,* Yao-Qin Feng, Xin-Xin Tian, Jun-Hao Wang,* Honggang Li, Gaoyi Han,* and Dan LiAbstract:Limited works are reported about off–on type mechanochromic luminogens (MLs) owing to notorious quenching effect and lacking of reliable guidance. Here a novel strategy is proposed to develop off–on type ML based on phenanthroimidazole (PI) derivative by controlling the intersystem crossing (ISC) process through variation of packing mode. This work offers a molecular level understanding of the cor

Heng Zeng, Weigang Lu,* Leiduan Hao, Gregory L Helms, Qiang Zhang,* Zhiping LuoAbstract:In this work, we demonstrated the successful synthesis of porous organic polymers via a ball-milling procedure. Several readily available benzene derivatives were selected to be polymerized through a Friedel–Crafts reaction with FeCl3 as the Lewis acid catalyst and formaldehyde dimethyl acetal as the crosslinker. All the mechano-synthesized porous organic polymers (MPOPs) are not soluble in common organic sol

Liping Zhao, Juan Qiao, Ke Zhang, Dan Li, Hongyi Zhang,* and Li Qi*Abstract:A chiral ligand exchange capillary electrochromatography (CLE-CEC) protocol was designed andimplemented for d,l-amino acids enantioseparation with poly(maleic anhydride-styrene-methacryloyl-l-arginine methyl ester) as the coating. The block copolymer was synthesized through the reversibleaddition fragmentation chain transfer reaction. In the constructed CLE-CEC system, poly (methacryloyl-l-arginine methyl ester) moiety o

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

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
