Azobenzene (AB) undergoes (E) (Z) isomerization upon exposure to light. Whereas the light-induced structural change can be exploited for numerous applications, a second, light-orthogonal switch would facilitate the development of new uses for AB derivatives. Electron-donating groups on the AB ring system change not only the absorption wavelengths, but also the isomerization properties. Experi
偶氮苯 (AB) 在曝光时发生 (E) (Z) 异构化。虽然光诱导的结构变化可用于多种应用,但第二个光正交开关将促进 AB 衍生物的新用途的开发。AB 环系统上的给电子基团不仅会改变吸收波长,还会改变异构化特性。体验
