Syntheses, Crystal Structure, and Photoluminescence Property of One Novel Compound Derived From Dicarboxylate and N-Donor Ligands

Abstract

One novel compound constructed from aromatic acid and N-heterocyclic ligands has been synthesized by hydrothermal reaction: [Mn(ipm)(1,8-NDC)(H2O)]2 (1) [ipm = 5-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)-2-methoxyphenol, 1,8-NDC = naphthalene-1,8-dicarboxylic acid]. The title compound was obtained by controlling the ratio of the starting materials and a reaction temperature at 170°C and was characterized by elemental analysis, IR, single-crystal X-ray diffraction, and thermogravimetric analysis (TGA). Single-crystal X-ray investigation reveals that compound 1 is zero dimensional (0D) structure, and the existence of hydrogen bonds and π-π interactions lead the 0D to 1D chain framework. Hydrogen bonds interactions are powerful noncovalent intermolecular interactions for directing supramolecular architectures. TGA shows three clear courses of weight loss, which corresponds to the decomposition of different ligands. At room temperature, compound 1 exhibits emission at 535 nm upon excitation at 325 nm. Fluorescent spectrum displays that compound 1 is potential luminescent material.
