A quantitative study of solvent environment effects on the photo-physical properties of a group of polymeric cyano azo benzene compounds was carried out at room temperature. Absorption and emission spectra of this group of azo matter with similar structure and different statistical weight of azo block have been studied in different solvents. The solvatochromic method was used to estimate the dipole moments in ground and excited states. The nature and degree of solvent-solute interactions were characterized using Kamlet-Abboud-Taft multi-parameter polarity scale.
室温下对一组聚合氰基偶氮苯化合物的溶剂环境效应的光物理性质进行了定量研究。研究了具有相似结构和不同偶氮嵌段统计权重的这组偶氮物质在不同溶剂中的吸收和发射光谱。用溶致变色法估计了基态和激发态的偶极矩。使用 Kamlet-Abboud-Taft 多参数极性标度来表征溶剂-溶质相互作用的性质和程度。
