Abstract
A polymorph of a [Zn(2)(IM)(4)·(DMF)] (IM: imidazolate; DMF: dimethyl formamide) framework was synthesized using a DMF template. The topology of a ZnN(4) framework is similar to that of zeolites with a chain of connected SiO(4) tetrahedra. This polymorph has a zeolite-like structure and a wave shape topology in the [010] direction. The main chain is connected to an imidazolate ligand. The structure has excellent chemical and thermal stability. This framework also exhibits broad range near-UV excitation from 350 nm to 430 nm and broadened photoluminescence emission at 445 nm. It has great potential as a phosphor in applications of near-UV or UV white light-emitting diodes.
