Abstract

The present invention discloses a neutrality-amphotericity bonded divalent non-linear optical chromophore group, the structural formula of which is shown in the formula (1). By applying the method of covalent bonding, the donors of two neutral chromophore groups are linked with the receptor of a zwitterionic chromophore group to produce a ramiform chromophore group. The neutrality-amphotericity bonded divalent non-linear optical chromophore group of the present invention is characterized in high hyperpolarizability, low dipole moment and high thermo-decomposing temperature.

Description

technical field [0001] The invention relates to a neutral-amphiphore bonded second-order nonlinear optical chromophore and a synthesis method thereof. Background technique [0002] Since the invention of laser in 1961, research work on nonlinear optics (NLO) materials has been started. The research of NLO can be summarized as the following two aspects: one is the discovery of NLO phenomena and effects, ascertaining their mechanism and regularity, and developing new NLO technologies and materials; the other is the application of NLO effects and technologies, such as Adaptive optics technology, integrated optics, optical storage and real-time holographic display technology, optical soliton communication technology, etc. [0003] Today, information and communication technologies are developing rapidly, and laser and optical fiber communication technologies are emerging communication technologies that replace microelectronics and integrated circuit technologies. The use of elec...
