N ‐Benzyl aroyl‐S ,N ‐ketene acetals can be readily synthesized by condensation of aroyl chlorides and N ‐benzyl 2‐methyl benzothiazolium salts in good to excellent yields, yielding a library of 35 chromophores with bright solid‐state emission and aggregation‐induced emission characteristics. Varying the substituent from electron‐donating to electron‐withdrawing enables the tuning of the solid‐state
N-苄基芳酰基-S , N-烯酮缩醛可以通过芳酰氯和N-苄基 2-甲基苯并噻唑鎓盐的缩合很容易地合成,产率良好至优异,产生具有明亮固态发射和聚集的 35 个发色团库。感应发射特性。将取代基从给电子改为吸电子,可以将固态发射颜色从深蓝色调整为红色。
