Enhanced Emission under Mechanical Stimuli Based on Phenanthroimidazole Derivative by Controlling ISC Process
41次浏览
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

Construction of chiral ligand exchange capillary electrochromatography for d,l-amino acids enantioseparation and its application in glutaminase kinetics study
35次浏览
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

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

A size-matched POM@MOF composite catalyst for highly efficient and recyclable ultra-deep oxidative fuel desulfurization
48次浏览
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
