Abstract

The invention provides an organic second-order nonlinear optical chromophore having a double-donor structure. The organic second-order nonlinear optical chromophore having the double-donor structure has a structure as shown below in the specification, wherein R1 is methyl or trifluoromethyl; and R2 is alkyl or phenyl. After an electron donor having the double-donor structure, a conjugate pi electron bridge and an electron acceptor, which are used by the invention, are combined together, the intramolecular electron transmission capability is enhanced, and the electrooptic coefficient can be increased. Besides, the synthesized chromophore has the double-donor structure, thereby effectively reducing the intermolecular interaction force. The organic second-order nonlinear optical chromophore is doped with amorphous polycarbonate to realize synthesis of a polymer film, and the polymer film can be used as a synthetic optical signal modulation material.

Description

technical field

[0001] The invention relates to the field of organic second-order nonlinear optical materials, in particular to an organic second-order nonlinear optical chromophore with a double-donor structure and its synthesis method and application. Background technique

[0002] With the rapid development of the information age, the requirements for communication and information materials are getting higher and higher at this stage. Nonlinear optical materials have attracted research interest in recent decades due to their great application prospects in practical fields such as optical communication, optoelectronics, and optical information processing. At present, the second-order nonlinear optical materials that have been commercialized are mainly inorganic materials, but inorganic materials have defects such as small electro-optical coefficients and long response times, which limit their wide application. It has been found that organic nonlinear optical materials have...
