In the right light: UV light triggers bond breaking, liberates a caged carboxylic acid, and generates the central CC double bond in the photoresponsive hexatriene molecule of a dithienylethene molecular switch. Light of the same wavelength converts the colorless isomer into its colored counterpart (see picture) in a visually convenient method to report on the success of the release event.
在正确的光线下:紫外线触发键断裂,释放出笼蔽的羧酸,并在二噻吩乙烯乙烯分子开关的光响应性六三烯分子中产生中心CC双键。相同波长的光可以通过视觉上方便的方法将无色异构体转换为有色对应物(参见图片),以报告释放事件是否成功。
