Better switching: The introduction of bulky substituents into the bridge moiety of dithienylethenes led to derivatives exhibiting high photocyclization quantum yields. This novel and versatile form of substitution facilitated tuning of the switching performance without compromising on the optical and redox properties of the ring‐open and ring‐closed forms (see scheme).
更好的转换:将大的取代基引入二噻吩基乙烯的桥基部分导致衍生物表现出高的光环化量子产率。这种新颖而通用的替代形式有助于调节开关性能,而不会影响开环和闭环形式的光学和氧化还原特性(请参见方案)。
