Abstract

AbstractThe microporous metal‐organic framework Cd2(ABTC)(H2O)(DMA)2·H2O·3DMA (1) (H4ABTC = 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 ABTC4– units with 4‐connected tetrahedral dinuclear Cd2(CO2)4(H2O)(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.
