Fusion selenophene endows the chromophore with more intrinsic and special functions. Herein, nonsymmetric selenophene-fused BODIPYs were designed and synthesized starting from the selenophene unit. The fused ring of selenophene not only maintains the rigid structure of BODIPY but also further modulates its spectral properties. The newly prepared dyes possessed many promising properties including large
融合硒吩赋予发色团更多的内在和特殊功能。在此,从硒吩单元开始设计并合成了非对称硒吩稠合 BODIPY。硒吩的稠合环不仅保持了 BODIPY 的刚性结构,还进一步调节了其光谱特性。新制备的染料具有许多有前途的特性,包括大摩尔消光系数、低荧光量子产率和适度的单线态氧生成。量子计算证实,较小的单线态-三线态能隙和较大的自旋轨道耦合导致有效的系统间交叉,从而提高单线态氧的产生率。此外,硒吩融合的 BODIPY 表现出显着的光毒性,而暗细胞毒性可忽略不计,
