A modular approach has been adopted to synthesize a wide range of visible light-driven photoswitchable azoheteroarenes. In this regard, we considered substitution of cyclic amines in the aryl ring and varied substitution patterns. Using detailed spectroscopic studies, we established a relationship between structure and photoswitching ability and also half-lives of the -isomers. Through this, we envision tunable and bidirectional longer wavelength photoswitches.
已经采用了模块化方法来合成广泛的可见光驱动的光致变色偶氮杂芳族化合物。在这方面，我们考虑了芳环中环状胺的取代和取代模式的变化。通过详细的光谱研究，我们建立了结构与光致变色能力以及 -异构体半衰期之间的关系。通过这种方式，我们设想了可调谐和双向的长波长光开关。
