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.
