A novel metal–organic framework based on bismuth and trimesic acid: synthesis, structure and properties

Abstract

A bismuth based metal-organic framework ([Bi(BTC)(DMF)]·DMF (CH3OH)2, Bi-BTC) with a novel topology structure is synthesized by a solvothermal method. Bi-BTC crystalizes in the P21/n space group, exhibits a novel 3D framework consisting of trimesic acid (H3BTC) linked with {Bi2O14} units and contains two helix chains which assemble regularly. In addition, we investigated the photophysical properties of Bi-BTC which shows high activity of O2 production in photocatalysis.
