摘要: We developed new benzofurazan (NBD) labeled probes for fluorocarbon surfactant systems. The fluorescence behavior depended on the solubilization site of fluorescent in aggregates. NBD-labeled suffered virtually complete reduction presence Na2S2O4 owing to at surface 2-hydroxy-1,1,2,3,3-pentahydroperfluoroundecyldiethylammonium bromide (FC8DAB) On other hand, N-(3-sulfopropyl)acridinium (SPA) FC8DAB aggregates showed residual spite NaBH4 addition. large vesicles were confirmed by DLS measurements. These facts suggest that SPA is solubilized an inner water phase vesicles. NBD probe quite effective study aggregation surfactants.
