Abstract

With the in situ-formed [MDMAP]+ (MDMAP+ = 1-methyl-4-dimethylaminopyridine) cations as structure-directing agents, a new chain-typed iodoplumbate hybrid, i.e., [MDMAP]PbI3 (1) has been solvothermally obtained and structurally characterized. Compound 1 belongs to the Pbca (No. 61) space group and has an infinite one-dimensional (1 D) [Pb2I6] n 2 n − anionic chain. Interestingly, it exhibits the semiconductor behavior with the band gap of 2.82 eV, which endows it with rapid and conspicuous photocurrent response property. Presented in this work also includes its thermal stability, X-ray photoelectron spectroscopy characterization and theoretical studies.
