Synthesis, Crystal Structure, and Luminescent Properties of Novel Zinc Metal–Organic Frameworks Based on 1,3-Bis(1,2,4-triazol-1-yl)propane

Abstract

Three new zinc three-dimensional coordination polymers with flexible 1,3-bis(1,2,4-triazol-1-yl)propane ligand were synthesized. The crystal structures of synthesized compounds were determined, and structural peculiarities are discussed. Coordination compounds with composition [Zn(btrp)(bdc)]·nDMF are interpenetrated frameworks, while metal–organic framework (MOF) [Zn3(btrp)(bdc)3]·nDMF is not. Thermal stability and luminescent properties of synthesized compounds have been investigated. The possibility of usage of such compounds as sensitive materials for some aromatic compounds are explored, and it was shown that luminescence of coordination polymers is completely quenched in the presence of nitrobenzene. Sorption properties of synthesized MOFs toward nitrogen, carbon dioxide, and hydrogen were evaluated.
