摘要: 本文设计、合成了一系列新型的三重态光敏功能性表面活性剂——对苯甲酰苄基三烷基溴化铵(简称PKT)。测定了它们的吸收光谱和发光光谱,比较了它们分子聚集形成胶束前后的光谱性质,结果表明,在均相溶液中光敏基团保持原有光敏剂分子的光谱性质。但在水溶液中,在形成胶束临界浓度前后,BP基团的光谱性质发生突变,峰值发生红移并强度减弱。在非水溶液中,由于功能性表面活性剂是逐步缔合过程,光谱性质发生逐步变化。

Abstract: A series of triplet photosensitive functional surfactants with (benzoylbenzyl) trialkylam-monium bromide (PICT) as head group were synthesized. The absorption and emission spectra of these compounds were measured. The results indicate that the BP group linked to surfactants maintains its original spectral properties in homogeneous media, but the properties change dramatically in both peak position and intensity while the functional surfactants form micelle at CMC. Owing to the progressive aggregation of the functional surfactants in organic solvents, the spectral properties of BP change gradually.
