series of eight novel T-shaped chromophores with indan-1,3-dione central acceptor moiety and peripheral N,N-dimethylamino and thiophene donors were synthesized. 4,7-Diiodoindan-1,3-dione was prepared in a straightforward manner from phthalanhydride. Its modification with donors was accomplished by Knoevenagel, Suzuki–Miyaura, and Sonogashira reactions. Target push–pull chromophores were further investigated
摘要 合成了一系列八个具有茚满-1,3-二酮中心受体部分和周边N,N-二甲基氨基和噻吩供体的新型T型发色团。由邻苯二甲酸酐以直接方式制备4,7-二碘茚满-1,3-二酮。用供体对其的修饰是通过克诺文塔格尔,铃木-宫浦和Sonogashira反应完成的。通过X射线分析,UV / Vis光谱和理论计算进一步研究了目标推挽发色团。 合成了一系列八个具有茚满-1,3-二酮中心受体部分和周边N,N-二甲基氨基和噻吩供体的新型T型发色团。由邻苯二甲酸酐以直接方式制备4,7-二碘茚满-1,3-二酮。用供体对其的修饰是通过克诺文塔格尔,铃木-宫浦和Sonogashira反应完成的。通过X射线分析,UV / Vis光谱和理论计算进一步研究了目标推挽发色团。
