Abstract

The invention belongs to the field of transition metal polymers, and in particular relates to a three-dimensional coordination polymer nonlinear optical material of which the chemical formula is {[Mn(HPIDC)](H2O).2H2O}n, wherein in the formula, HPIDC is divalent anion of 2-(4-pyridyl)-1H-imidazole-4,5-dicarboxylic acid. The secondary harmonic effect (SHG) of the three-dimensional coordination polymer nonlinear optical material is 1.5 times of that of a standard sample potassium dihydrogen phosphate (KDP), and the three-dimensional coordination polymer nonlinear optical material has certain second-order nonlinear properties, has the potential to be a nonlinear optical material, and has wide application prospects in fields such as optical information storage, laser communication, electronic instruments and medical instruments.

Description

technical field [0001] The invention belongs to the technical field of transition metal coordination polymer materials, and in particular relates to a three-dimensional coordination polymer nonlinear optical material and a preparation method thereof. Background technique [0002] With the vigorous development of optoelectronic technology, nonlinear optical crystal materials have broad application prospects in communication, laser, optical information storage and other fields. Coordination polymers combine the advantages of inorganic and organic nonlinear materials, can regulate the geometric configuration of the metal center and the coordination directionality of metal-organic ligands, and directionally synthesize non-centrosymmetric skeleton materials. hotspot. In recent years, some progress has been made in the research of coordination polymers as nonlinear optical materials (YeQiong, Li Yong-Hua, Song Yu-Mei, Huang Xue-Feng, Xiong Ren-Gen, Xue Ziling, Inorg. Chem., 20...
