摘要

The microporous metal-organic framework Cd_2(ABTC)(H_ 2O)(DMA)_2·H_2O·3DMA (1) (H_ 4ABTC = 3,3',5,5'-azobenzenetetracarboxylic acid; DMA = N,N'-dimethylacetamide) was prepared by solvothermal reaction and characterized. X-ray structure analysis revealed that compound 1 is a three-dimensional (3D) open framework with 2D channels. The topology is based on a PtS net, constructed of 4-connected rectangular ABTC~(4-) units with 4-connected tetrahedral dinuclear Cd_2(CO_2)_4(H_2O)(DMA)_ 2 secondary building units (SBUs). The solid-state excitation-emission spectra showed that the strongest emission peak is at 403 nm upon excitation at λ = 287 nm.
