In present work, photodissociation kinetics of selective CC bond in BBM is investigated in different micelles concentration. In polar solvents, rate of photodissociation (k) is relatively lower compared to H2O solvent under similar condition. The rate of photodissociation (k) is enhanced with increase of aqueous CTAB concentration and found to be highly sensitive to aqueous CTAB concentration. It is clear that micelle concentration and hydrophobic region plays significant role on enhancing rate of photodissociation. Crucial role of hydrophobic region in micelle has been discussed and confirmed by experimental results.

双胶束环境中双-2-亚苄基丙二腈(BBM)的光解离和动力学
在目前的工作中,在不同的胶束浓度下研究了BBM中选择性C C键的光解离动力学。在极性溶剂中,在类似条件下,光解离速率(k)与H 2 O溶剂相比相对较低。随着水CTAB浓度的增加,光解离速率(k)增加,并且发现其对CTAB水溶液高度敏感。显然,胶束浓度和疏水区在提高光解离速率方面起着重要作用。疏水区在胶束中的关键作用已被讨论并得到实验结果的证实。
