Abstract

The invention provides a phthalocyanine-graphene oxide composite nonlinear optical material and a preparation method thereof, and belongs to the field of composite nonlinear optical materials. The problem of relatively poor third-order nonlinear optical performance of the existing nonlinear optical materials is solved. The preparation method comprises the following steps: 1. adding 2,3,6-tricyanophthalene, metal zinc salt and 1,8-diazabicycloundecyl-7-alkene to a reaction bottle, using n-pentanol as a reaction solution, performing a heating reflux reaction, adding acetic acid at the end of thereaction, cooling to the room temperature, performing methanol centrifugation to collect a solid phase, and adding concentrated sulfuric acid to perform a heating hydrolysis reaction to obtain tetracarboxy metal naphthalocyanine; and 2. adding the tetracarboxy metal naphthalocyanine and GO into the reaction bottle, using N, N- dimethylformamide as a reaction solution, and stirring to generate a reaction to obtain the phthalocyanine-graphene oxide composite nonlinear optical material.

Description

technical field [0001] The invention belongs to the field of composite nonlinear optical materials, in particular to a naphthalocyanine-graphene oxide composite nonlinear optical material and a preparation method thereof. Background technique [0002] With the development of optical research, especially the gradual maturity of laser technology, materials with excellent nonlinear optical properties have become one of the hot spots of scientific research. Graphene oxide (GO) has good application prospects in the field of nonlinear optics due to its excellent nonlinear optical properties, but its poor solubility limits its application in popular fields. Therefore, the improvement of the properties of graphene oxide by introducing water-soluble groups is the focus and focus of current research. [0003] Among the functional groups contained in the surface layer of graphene oxide, less electron-donating groups are contained, which limits its important role in the electron transf...
