The present work describes the synthesis and characterization of pyrene derivatives, N-(1-Pyrenoylmethyl) pyridinium bromide (PM-PB) and N-(1-Pyrenoylmethyl)-N,N,N-triethylammonium bromide (PM-TAB). The photophysical behavior of these molecules has been studied in various protic and aprotic solvents. Using steady state fluorescence intensity, fluorescence anisotropy and dynamic fluorescence lifetime studies, the sensitivity of these molecules towards the micellization process of bile salts has been monitored. These derivatives have been effectively used in estimating critical micellar concentration (CMC) of bile salt, sodium deoxycholate (NaDC).
本工作描述了芘衍生物 N-(1-芘甲酰基)吡啶溴化物 (PM-PB) 和 N-(1-芘甲酰基)-N,N,N-三乙基溴化铵 (PM-TAB) 的合成和表征。这些分子的光物理行为已在各种质子和非质子溶剂中进行了研究。通过稳态荧光强度、荧光各向异性和动态荧光寿命研究,监测了这些分子对胆盐胶束化过程的敏感性。这些衍生物已有效地用于估计胆盐(脱氧胆酸钠)NaDC 的临界胶束浓度(CMC)。
