Jie Liu,⊥Jia-Jia Du,⊥Yuan Wu, Yi-Fang Zhao, Xiao-Ping Zhou,* and Dan Li* Abstract:Two one-dimensional (1D) helical coordination polymers, CuBIm–Cl and CuBIm–Br (BIm = 1,2-bis((5H-imidazol-4-yl)-methylene)hydrazine), are constructed from Cu2+ ions, halides and mono-deprotonated BIm. Solid-state crystalline conversions of CuBIm–Cl and CuBIm–Br to a gyroidal metal–organic framework (MOF) STU-3 which is composed of Cu ions and Bim ligands are observed through a gas–solid reaction, where the gas is m

Hong Cai, Li-Li Xu, He-Yun Lai, Jing-Yi Liu,b Seik Weng Ng and Dan Li *Abstract:A new adenine-containing metal–organic framework (MOF), [Zn4O-(adenine)4(benzene-1,3-dicarboxylate)4Zn2] (named as ZnBDCA), was synthesized solvothermally. ZnBDCA possesses high quantum yield (450%) and nano-channels that can encapsulate acriflavine molecules to build a host–guest chemopalette for approaching white-light emission.文章链接:c7cc03350h.pdf

Jun-Hao Wang,* Ying Zhang, Mian Li, Shu Yan, Dan Li, and Xian-Ming Zhang*Abstract:Chromium(III)-based metal–organic frameworks (Cr-MOFs) are very attractive in a wide range of investigations because of their robustness and high porosity. However, reports on Cr-MOFs are scarce owing to the difficulties in their direct synthesis. Recently developed postsynthetic routes to obtain Cr-MOFs suffered from complicated procedures and a lack of general applicability. Herein, we report a highly efficient a

Shun-Ze Zhan,* Mian Li, Ji Zheng, Qiu-Juan Wang, Seik Weng Ng, and Dan Li*Abstract:Six daughter complexes based on two-dimensional (2-D) luminescent Cu4I4−Cu3Pz3 (Pz = pyrazolate) coordination networks, which exhibit an uncommon Cu4I4L3L′ (L = pyridine; L′ = acetonitrile, pyridine, pyrazine, 1,4-diazabicyclo[2.2.2]octane, triphenylphosphine, none) local configuration, were prepared through a postsynthetic modification method starting from a parent complex (L′ = NH3). This work has successfully i

Jun-Hao Wang, Dong Luo, Mian Li, and Dan Li*Abstract:This account demonstrates that under regulated synthetic conditions the protonated carboxyl sites in a neutralmetal−organic framework (MOF), known as MOF-324 [formulated as Zn3OH(PzC)2(HPzC), H2PzC = 4-pyrazolecarboxylic acid], can undergo complete deprotonation, yielding NH4@ZnPzC[formulated as NH4·Zn3OH(PzC)3]. This modified, anionic framework with a pcu-g net is thus capable of postsynthetic cation exchange,which is highly modular, encompas

Zhiyu Jia, Zicheng Zuo, Yuanping Yi, Huibiao Liu, Dan Li, Yongjun Li, and Yulian Li*Abstract:Carbon Ene-yne (CEY), a novel two-dimensional full carbon material, was synthesized from tetraethynylethene.Compared with the traditional preparation method of carbon materials, CEY was synthesized by chemical method in solvent-phase under mild condition (low temperature, atmospheric pressure). Diyne of CEY were connected through vinyl groups which is help for π-electron transition, thus this new materia
