摘要
自从１９３８年，Ｓｃｈｅｉｂｅ［１］发现了菁染料聚集体中的能量传递现象，人们对菁染料的聚集行为展开了大量的研究［２，３］．由于菁染料聚集体对乳剂具有特殊的增感作用，人们主要研究聚集体在乳剂中的增感机理［４，５］以及菁染料聚集的溶剂效应与浓度效应［６］...
Two anionic carbocyanine dyes, 5,5' bis trifluoromethyl 1,1' diethyl 3,3' bis (3 sulfopropyl) benzimidazolocarbocyanine sodium salt, 1' ethyl 3,3' bis (3 sulfopropyl) 5 chloro 5' trifluoromethyl benzimidazolo oxa carbocyanine, and their intermediates were synthesized. Their structures have been characterized by infra red spectroscopy (IR), nuclear magnetic resonance ( 1 H NMR) and mass spectroscopy (MS). UV vis spectra of these two dyes have been determined in 1,2 dichloroethane. It was found that these two dyes had different behavior of aggregation reaction. Moreover, dynamics of aggregation reaction of these two dyes has been studied.
