讨论了胶束体系中的各种动力学过程,并将其联系在一起。这些事件的时域从热反应的几秒到光电离过程的<10/sup -14/秒不等。所描述和讨论的动力学过程有:(1)单体表面活性剂分子与胶束之间的实际动力学平衡;(2)控制探针分子在胶束中进出速率的特征;(3)分子在胶束中的运动;(4)胶束表面溶解的分子间电子传递;(5)从胶束中的探针分子中射出一个电子进入水相。讨论说明了胶束的许多有趣的特征,由此辐射诱导的反应可以被催化或反应途径定向。对反胶束中类似事件的简要描述结束了讨论。在这些系统中,人们特别注意到气泡的独特特征以及它们从大块烷烃相中有效捕获电子的能力。13张图,3张表。
Various kinetic processes in micellar systems are discussed and related together. The time domain of these events varies from seconds for thermal reactions to <10/sup -14/ sec for photoionization processes. The kinetic processes described and discussed are: (1) the actual kinetic equilibria between monomer surfactant molecules and micelles; (2) the features that control the rates of entry and exit of probe molecules in micelles; (3) the movement of molecules in micelles; (4) the electron transfer between molecules solubilized at the micelle surface; and (5) the ejection of an electron from a probe molecule in the micelle into the aqueous phase. The discussion illustrates many of the interesting features of micelles whereby radiation induced reactions may be catalyzed or the reaction pathway directed. A brief description of similar events in reversed micelles concludes the discussion. In these systems particular attention is drawn to the unique features of the water bubbles and their ability to efficiently capture electrons from the bulk alkane phase. 13 figures, 3 tables.
