Excited state chemistry and physics of molecules, in addition to their inherent electronic and steric features, depend on their immediate microenvironments. This study explores the influence of an organic capsule, slightly larger than the reactant molecule itself, on the excited state chemistry of the encapsulated molecule. Results presented here show that the confined molecule, in fact, is not isolated and can be manipulated from outside even without direct physical interaction. Examples where communication between a confined molecule and a free molecule present outside is brought about through electronic and energy transfer processes are presented. Geometric isomerization of octa acid encapsulated stilbenes induced by energy and electron transfer by cationic sensitizers that attach themselves to the anionic capsule is examined. The fact that isomerization occurs when the sensitizer present outside is excited illustrates that the reactant and sensitizer are communicating across the molecular wall of the capsule. Ability to remotely activate a confined molecule opens up new opportunities to bring about reactions of confined radical ions and triplet excited molecules generated via long distance energy and electron transfer processes.

遥远的电子和能量转移敏化了包封的斯蒂苯酯的光异构化。

分子的激发态化学和物理学，除了其固有的电子和空间特征外，还取决于其直接的微环境。这项研究探索了比反应物分子本身稍大的有机胶囊对被包封分子的激发态化学的影响。此处显示的结果表明，实际上，受限分子不是孤立的，即使没有直接的物理相互作用也可以从外部进行操纵。给出了通过电子和能量转移过程在外部存在的受限分子和自由分子之间进行通信的例子。研究了由自身附着在阴离子胶囊上的阳离子敏化剂的能量和电子转移引起的八酸封装的斯蒂苯酯的几何异构化。当存在于外部的敏化剂被激发时发生异构化的事实说明，反应物和敏化剂在胶囊的分子壁上连通。远程激活受限分子的能力为引起受限自由基离子和三重激发分子产生反应提供了新的机会通过长距离能量和电子转移过程。
