Dong Luo, Xiao-Ping Zhou,* and Dan Li*Abstract:Biological function arises by the assembly ofindividual biomolecular modules into large aggregations orhighly complex architectures. A similar strategy is adopted in supramolecular chemistry to assemble complex and highly ordered structures with advanced functions from simple components. Here we report a series of diamond-like supramolecular frameworks featuring mesoporous cavities, which are assembled from metal-imidazolate coordination cages and v

Raymond Wai-Yin Sun,* Ming Zhang, Dan Li,* Mian Li, and AliceSze-Tsai WongAbstract:An anti-cancer active gold(III) pyrrolidinedithiocarbamato complex [(PDTC)AuIIICl2] (1) has been synthesized and characterized by means of X-ray crystallography. Compared to the pyrrolidinedithiocarbamate ligand itself,this gold(III) complex displays an up to 33-fold higher anti-cancer potency towards a panel of cancer cell lines including the cisplatin-resistant ovarian carcinoma cell line (A2780cis). As demonstr

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

A gold(i)–pyrazolato complex as a switch-on luminescent probe for cysteine: in situ formation of fluorescent nanoparticles and rose-like microspheres

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
