Abstract

The authors study the spectral behavior of D–π–A type styryl dye of the quinoline series in solvents of different natures. Pronounced solvatochromism and sensitivity to the medium’s viscosity are discovered. Microcrystalline dye powder is studied using chromium-forsterite laser radiation with a wavelength of 1250 nm. The observed differences in second-order nonlinearity correlate with structural differences in analogous compounds, and with factors of organizing the supramolecular system in the crystal.

吡啶和喹啉系列二甲基胺取代苯乙烯染料的结构差异对微晶粉末中二阶和三阶非线性的影响

作者研究了喹啉系列 D-π-A 型苯乙烯染料在不同性质溶剂中的光谱行为。发现了明显的溶解变色现象和对介质粘度的敏感性。使用波长为 1250 nm 的铬萤石激光辐射对微晶染料粉末进行了研究。观察到的二阶非线性差异与类似化合物的结构差异以及晶体中超分子系统的组织因素相关。
