英文摘要	From a new rigid N-donor ligand, 3,6-di(1H-imidazol-1-yl)-9H-carbazole (L), two coordination polymers (CPs) formulated as CdL(L1)3DMF (1; H(2)L1 = 4,4-carbonyldibenzoic acid, DMF = N,N-dimethylformamide) and Cu2L2(SO4) (2) were synthesized solvothermally and structurally characterized by single-crystal X-ray diffraction. CP 1 exhibits a two-dimensional (2D) structure, and CP 2 shows one-dimensional (1D) chains. The two CPs exhibit different quasireversible redox properties and possess very weak photoluminescence properties. Density functional theory (DFT) calculations and experimental results show that CP 1 has a wider band gap than that of CP 2. Notably, CP 2 produces a higher photocurrent density than that of CP 1 upon visible-light illumination, which is also in agreement with their Nyquist plots and Mott-Schottky curves. Thin-film CP 1 was obtained by physical exfoliation in methanol and shows more active electrochemical behavior and enhanced photoresponse relative to those of bulk CP 1.; National Natural Science Foundation of China [21371184]; Large-Scale Instrument and Equipment Open Foundation of Chongqing University [201606150053]; Science and Technology Research Foundation of the Education Commission of Chongqing [KJ1501124]; Chongqing Key Laboratory of Chemical Process for Clean Energy and Resource Utilization; SCI(E); ARTICLE; gongyun7211@cqu.edu; jhlin@pku.edu.cn; 30; 4928-4936
