摘要

偶极子azinylmethylenemononn腈基发色团具有多种融合的azine（喹啉、喹啉和吡啶[2,3-b]吡嗪）基团和苯胺供体片段中庞大的tbdps -乙基。用二次谐波产生技术和两种方法研究了掺杂这类染料的极化PMMA薄膜的非线性光学活性。当染料负载从25 wt%增加到35 wt%时，复合材料表现出NLO性能的增长。掺杂喹啉基甲基肠酮腈基发色团的聚合物薄膜的NLO系数d33提高到85 pm /V。

Dipole fused (azinylmethylene)malononitrile-based chromophores with TBDPS group: increase of nonlinear optical performance of polymer films at high dopant content

Dipole azinylmethylenemalononitrile-based chromophores with various fused azine (quinoline, quinoxaline and pyrido[2,3-b]pyrazine) moieties and bulky TBDPS-ethyl group in aniline donor fragment have been synthesized. Nonlinear optical (NLO) activity of poled PMMA films doped with such dyes has been investigated by second harmonic generation technique with in two approaches. Composite materials exhibit the growth of NLO performance at increasing dyes load from 25 wt% to 35 wt%. Polymer films doped with quinoxalin(on)ylmethylenemalononitrile-based chromophores demonstrate enhanced values of NLO coefficients, d₃₃, up to 85 p.m./V.

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
