The photochemical processes of singlet-singlet energy transfer and photoinduced electron transfer are important not only in natural and artificial photosynthetic energy conversion, but also in a variety of other scientific and technological applications. Controlling these functions at the molecular level using outside stimuli is an interesting scientific challenge. Photochromes, organic molecules that are isomerized by light between two stable forms, can be covalently linked to other chromophores, and changes in their properties resulting from photoisomerization used to switch electron and energy transfer on or off. Simple single- and double-throw molecular switches have been constructed, as well as Boolean logic gates. Such molecules are potentially useful in light-controlled molecular data processing and storage applications.
单线态-单线态能量转移和光致电子转移的光化学过程不仅在自然和人工光合能量转换中很重要，而且在各种其他科学技术应用中也很重要。利用外部刺激在分子水平上控制这些功能是一项有趣的科学挑战。光致变色化合物是在两种稳定形式之间通过光异构化的有机分子，可以与其他发色团共价连接，并且利用光异构化引起的其性质变化来开启或关闭电子和能量转移。已经构建了简单的单刀和双刀分子开关以及布尔逻辑门。这类分子在光控分子数据处理和存储应用中可能很有用。
