The development of mechanochromic fluorophors with high-brightness, solid-state fluorescence is very significant and challenging. Herein, highly solid-state emissive triphenylamine, carbazole and tetraphenylethylene-functionalized benzothiadiazole derivatives were developed. These compounds showed remarkable aggregation-induced emission and solvatochromic fluorescence characteristics. Furthermore, these fluorogenic compounds also displayed different mechanically triggering fluorescence responses.
开发具有高亮度固态荧光的机械变色荧光体意义重大,极具挑战性。在此,我们开发了高固态发射的三苯胺、咔唑和四苯基乙烯官能化苯并噻二唑衍生物。这些化合物显示出显著的聚集诱导发射和溶解变色荧光特性。此外,这些致氟化合物还显示出不同的机械触发荧光反应。
