罗丹明6G与罗丹明B之间的能量转移和吖啶橙形成聚态的现象用于研究长链烷基硫酸钠(C~nH~2~n~+~1OSO~3Na,n=12,14和16)在水溶液中预胶束的生成。结果表明,烷基链的长度影响这些表面活性剂形成预胶束的能力,碳数的增加使预胶束形成浓度降低。

The phenomena of energy transfer between Rhodamine 6G and Rhodamine B, and aggregate formation of Acridine Orange were used as probe for studying the premicellar formation of long-chain C~nH~2~n~+~1OSO~3Na molecules in water solution. The results showed that the length of alkyl chain influences on the ability of premiceller formation of these surfactants. The increase of carbon number of alkyl chain leads to the decrease of concentration of premicellar formation.
