Solvothermal Syntheses, Crystal Structures, and Luminescent Properties of Two New Cadmium(II) Coordination Polymers Based on Rigid/Flexible Dicarboxylate and N,N '-Bis(4-PYridyl)-1,4,5,8-naphthalenetetracarboxydiimide

摘要

In order to investigate the effect of the organic ligands on the structures of coordination polymers, two new cadmium(11) coordination polymers based on the different dicarboxylate ligands, namely [Cd-2(bpdc)(2)(DPNDI)(2)]center dot 3H(2)O center dot NME (1) and [Cd(obb)(DPNDI)] ( 2) [H(2)bpdc = biphenyl-4,4'-dicarboxylite, H(2)obb = 4,4'-oxybistbenzoic acid), DPNDI = N,N'-bis(4-pyridyl)-1,4,5,8-naphthalene tetracarboxy-diimide, and NMF = N-methylformamide), were synthesized under solvothermal condition and further characterized. Complex 1 shows a twofold interpenetrated pcu topology. Complex 2 possesses a two-dimensional (2D) layer structure with -ABCD- stacking sequence. Furthermore, the luminescent properties of complexes 1 and 2 are investigated.
