bearing various substituents were designed and synthesized. These azo dyes were characterized by spectroscopic techniques such as 1H/13C NMR and HRMS or LCMS. Photophysical, NLO and protonation properties were investigated by experimentally and theoretically. The absorption maxima were observed in long wavelength in DMSO. The most stable tautomeric form of dyes which have tautomeric forms, were determined
摘要 本论文设计合成了二苯胺与N-甲基二苯胺偶联制备的两个系列偶氮染料和带有各种取代基的重氮化取代苯胺。这些偶氮染料通过光谱技术如 1H/13C NMR 和 HRMS 或 LCMS 进行表征。通过实验和理论研究了光物理、非线性光学和质子化特性。在DMSO中在长波长处观察到吸收最大值。使用模型化合物确定具有互变异构形式的染料的最稳定的互变异构形式。结果表明,偶氮染料在所有使用的溶剂中均以偶氮形式稳定。对于合成染料作为光学染料的可用性,还确定了所有染料的热性能。所有化合物都是热稳定的,Td 值大于 220 °C。
