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 emission color from deep blue to red.
N-苄基芳酰基-S,N-亚氨代乙酮缩醛可通过芳酰氯与 N-苄基 2-甲基苯并噻唑鎓盐缩合反应以良好至优异的产率轻易合成，得到 35 个具有明亮固态发射和聚集诱导发射特性的生色团库。改变取代基的电子给体到电子受体的性质，可使固态发射颜色从深蓝色调至红色调。
