Description

technical field [0001] The invention belongs to the field of composite nonlinear optical materials, and in particular relates to a benzene ring-substituted phthalocyanine / 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. Both phthalocyanine and graphene oxide are good third-order nonlinear optical materials, and the nonlinear optical composite materials with better performance can be formed by covalent bonding between the two. However, there are few reports on the correlation between the molecular structure of phthalocyanine and the nonlinear optical properties of phthalocyanine / graphene oxide composites. [0003] Graphene oxide contains many oxygen-containing functional groups, which makes its chemical pro...
