In this study, highly solid-state emissive compounds based on triphenylamine, carbazole and tetraphenylethylene-functionalized benzothiadiazole derivatives were developed, exhibiting remarkable aggregation-induced emission and solvatochromic fluorescence characteristics. Moreover, these fluorogenic compounds displayed varied fluorescence responses upon mechanical triggering.
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.
