摘要

Under hydro/solvothermal conditions, the assembly of imidazole-containing ligand 1,3,5-tri(1-imidazolyl) benzene (tib) and 2,6-naphthalenedicarboxylic acid (H2NDC) with different transition metal salts provides five new coordination polymers [M-2(tib)(2)(NDC)(H2O)(2)] SO4 center dot XH2O (1: M = Cd, X = 4; 2: M = Co, X = 4; 3: M = Ni, X = 3), [Cd-2(tib)(2)(NDC)(NO3)(2)] 2.5DMF center dot H2O (4) (DMF = N, N-dimethylformamide) and [ Zn(tib) 2/ 3(NDC)] (5). 1-3 have the same three-fold interpenetrating 3D framework structures with SO42- as counteranion, while 4 with NO3- as terminal ligand exhibits a wave-like 2D layer structure, which is further extended into a 3D framework by hydrogen bonds. In addition, complex 5 obtained at high temperature is an interesting two-fold interpenetrating 3D structure. Sorption and photoluminescence properties of the complexes were investigated. 4 displays selective adsorption of CO2 over N-2. Furthermore, 1 and 4 can be used to probe acetone molecules selectively and rapidly via fluorescence quenching.
