以孔雀石绿绿色亮腈衍生物（MGL）为引发剂，研究了二（2-乙基己基）磺基琥珀酸钠（AOT）反胶束的光致破裂. UV照射溶解在AOT-水-氯仿混合物中的MGL产生与阴离子AOT静电相互作用的阳离子表面活性剂。我们研究了使用质子核磁共振光谱的反胶束的破坏，并发现，紫外线照射的MGL的AOT反胶束的内部溶解的水分子的数量减少。此外，反胶束的光诱导破坏被示出释放核糖核酸酶A，其被捕获在AOT反胶束内部的水中。这种光诱导的释放可以提供生物聚合物的期望的运输系统。
Photoinduced disruption of a sodium bis(2-ethylhexyl) sulfosuccinate (AOT) reverse micelle is triggered by a Malachite Green leuconitrile derivative (MGL). UV irradiation of MGL solubilized in an AOT-water-chloroform mixture creates a cationic surfactant that interacts electrostatically with the anionic AOT. We investigated the disruption of the reverse micelle by using proton nuclear magnetic resonance spectroscopy and found that UV irradiation of MGL decreases the number of water molecules solubilized in the interior of the AOT reverse micelles. Furthermore, the photoinduced disruption of the reverse micelle is shown to release ribonuclease A, which is trapped in the water in the interior of the AOT reverse micelle. This photoinduced release may offer a desirable transport system of biopolymers.
