近年来,对微环境效应的研究工作日益活跃.就各种表面活性物质在溶液中存在的胶束而言,其临界胶束浓度(cmc)、平均聚集数(N)、胶束内极性以及微观粘度等都已引起许多研究者的注意.最近的研究表明,在胶束形成前存在着一种预胶束(premicellar)山形成的区域.1982年我们已注意到,两种因浓度较低而不能发生能量转移的染料分子,在加入浓度远小于 cmc 值的少量表面活性剂后,就可以观察到能量转移.表明两种分子已处于同一集合体内.本工作以吖啶橙染料为探针,对上述问题作了进一步的探讨.
In recent years, research work on microenvironment effects has become more and more active.For micelles with various surfactant present in solution, the critical micelle concentration (cmc), the average aggregation number (N), the micellar internal polarity As well as the micro-viscosity have attracted the attention of many researchers.Recent studies show that there is a premicellar mountain formation area before the micelles formation.We have noticed in 1982 that the two different concentrations Low and can not occur energy transfer dye molecules, adding a concentration of much less than cmc value of a small amount of surfactant, you can observe the energy transfer, indicating that the two molecules are already in the same pool.In this work to acridine orange dye Needle, on the above issues for further discussion.
