Shi-Hong Lin, Mian Li, Dong Luo, De-Xiang Zhang, Tian Wen, Xiao-Ping Zhou, and Dan Li*Abstract:A novel isohedral 3-periodic net (i.e. a net with one kind of tile), showing a Cairo pentagonal tiling projection on the Euclidean plane, has been identified in a series of site-modified CuCN/CuSCN networks, namely, [Cu6(SCN)2(CN)6·Ni(tpy)2]n (1),[Cu6(SCN)(CN)7·Ni(tpy)2]n (2) and [Cu6(CN)8·Ni(tpy)2]n (3) (tpy=2,2’:6’’,2’’-terpyridine). These infinite inclusion compounds were prepared via a solvothermal

Yaroslav Grosu,* Mian Li, Yun-Lei Peng, Dong Luo, Dan Li, Abdessamad Faik, Jean-Marie Nedelec, and Jean-Pierre GrolierAbstract:A molecular spring formed by a hydrophobic metal–organic framework Cu2(tebpz) (tebpz=3,3’,5,5’-tetraethyl-4,4’-bipyrazolate) and water is presented. This nanoporous heterogeneous lyophobic system (HLS) has exceptional properties compared to numerous reported systems of such type in terms of stability, efficiency, and operating pressure. Mechanical and thermal energetic c

Raymond Wai-Yin Sun,* Ruo-Fan Xu, Huan-Quan Song, Camille Saint-Germain, Ming Zhang, Wen-Xiu Ni, Chun-Xia Chen, Catherine Hemmert, Heinz Gornitzka, and Dan Li* Abstract:A gold(I)–pyrazolato complex has been designed as a luminescent probe for cysteine (Cys). Spectroscopy and microscopy experiments revealed that the complex would disintegrate in the presence of Cys to form gold–Cys fluorescent nanoparticles, and was found to enhance Cys to form rose-like microspheres in solution.文章链接:c6qi00205f.p

Qiong Xiao, Yuan Wu, Mian Li, Michael O’Keeffe* and Dan Li*Abstract:The renowned aperiodic Boerdijk–Coxeter helix is identified, with a modified, periodic form, in a MOF named ROD-1 [formulated as Cd(L), H2L = (3,5-dimethyl-1H-(pyrazol-4-yl)-methylene)benzoic acid], which exhibits unusual gas adsorption behaviours attributed to guest–guest interactions, and also interesting structural dynamics responding to temperature variation and gas adsorption.文章链接:c6cc04912e.pdf

Yurui Xue, Jiaofu Li, Zheng Xue, Yongjun Li, Huibiao Liu, Dan Li, Wensheng Yang,*and Yuliang Li*Abstract:We have used a scalable and inexpensive method to prepare a catalyst comprising graphdiyne nanosheetsupported cobalt nanoparticles wrapped by N-doped carbon (CoNC/GD); this unprecedentedly durable electrocatalyst mediated the hydrogen evolution reaction (HER) with highly catalytic activity over all values of pH. The durability of the CoNC/GD structure was evidenced by the catalytic performanc

Zheng Xue, Hui Yang, Juan Gao, Jiaofu Li, Yanhuan Chen, Zhiyu Jia, Yongjun Li, Huibiao Liu,* Wensheng Yang,* Yuliang Li, and Dan LiAbstract:A new method of in situ electrically induced selfassembly technology combined with electrochemical deposition has been developed for the controllable preparation of organic/ inorganic core/shell semiconductor heterojunction nanowire arrays. The size of the interface of the heterojunction nanowire can be tuned by the growing parameter. The heterojunction nano
