Abstract

The invention relates to a porphyrin-structure-unit-containing porous network conjugated polymer and a preparation method thereof, belonging to the technical field of functional high-polymer materials. The invention aims to obtain a nonlinear optical material with higher chemical stability and heat resistance. The porous network conjugated polymer is formed by connecting a porphyrin structure unit to a high-polymer main chain framework. The preparation method comprises the following steps: carrying out polycondensation reaction on carboxyl porphyrin derivatives and small molecules containing diamido and dihydroxy groups to prepare the polymer. Compared with the porphyrin small molecules, the content of the pi-electron conjugated system is enhanced. When the porous network conjugated polymer is used as the nonlinear optical material, the macroscopic nonlinear coefficient and nonlinear optical properties of the material are greatly enhanced, and the porous network conjugated polymer has higher chemical stability and heat resistance. Therefore, the porphyrin-structure-unit-containing porous network conjugated polymer has wide application prospects in the fields of optoelectronic industry, micro-electronic industry, communication and the like when being used as the nonlinear optical material.
