英文摘要	Based on a rigid ligand, 2,5-bis[3'-carboxyl-phenyl] pyridine (H2L), two coordination polymers (CPs) formulated as Cd3L3(DMF)(4) (1) and CdL(DMF)center dot DMF (2) were solvothermally synthesized and characterized by single-crystal X-ray diffraction. CP 1 is a uninodal 6-connected 3D network with a {4(4).6(10).8}-mab topology, in which the Cd-3 unit with a Cd center dot center dot center dot Cd separation of 3.61 angstrom is observed. CP 2 exhibits a uninodal 2D layer with a 4(4)-sql topology, in which Cd(II) ions are linked into a Cd-O-Cd chain with a Cd center dot center dot center dot Cd separation of 3.91 angstrom. DFT calculations indicate that CP 1 possesses a more narrow band gap than CP 2, and CP 1 yields higher photocurrent density upon visible light illumination than CP 2. In the present work, the few-layered CP 2 has been in situ synthesized, and it shows enhanced photocurrent density with respect to the bulk CP, which is probably associated with the large fraction of uncoordinated surface atoms and dangling bonds in the nanosheet of CP 2.; National Natural Science Foundation of China [21371184]; Fundamental Research Funds for the Central Universities [CQDXWL-2012-024]; Chongqing University [201406150041]; Chongqing Key Laboratory of Chemical Process for Clean Energy and Resource Utilization; SCI(E); EI; ARTICLE; gongyun7211@cqu.edu.cn; jhlin@pku.edu.cn; 11; 4603-4613; 45
