Abstract

The invention provides an organic optical nonlinear chromophore based on a novel single donor self-assembly structure, and belongs to the field of optical materials, the chromophore has a structural formula as shown in an abstract figure, OH groups are introduced into a single donor and an electron bridge of a second-order nonlinear optical chromophore through nucleophilic reaction, and the chromophore has a structure shown in the description. The two OH groups provide connection sites for further modification, and through the access of different self-assembled isolation functional groups and the test of electro-optical coefficients, after the materials are self-assembled, compared with other non-self-assembled materials, the materials have higher electro-optical coefficients.

Description

technical field [0001] The invention relates to the field of organic optical materials, in particular to a dendritic self-assembled optical nonlinear chromophore and a synthesis method and application thereof. Background technique [0002] With the rapid development of information and communication technology, people's demand for high-speed data transmission, processing and large-capacity information computing is also increasing. Compared with traditional electronics as an information carrier, photons as a communication information carrier have good parallelism and fast speed. , large bandwidth, high frequency, strong anti-electronic interference ability, good confidentiality and so on. Among many communication technologies, photon, electronic and other technologies are closely related to electro-optic modulators, optical switches, optical information storage and other devices. The mutual conversion of electrical and optical signals has become an important part of today's co...
