A significantly red-shifted fluorescence and a high fluorescence quantum yield for the emission from the twisted intramolecular charge transfer (TICT) state are attained in new aminoboranes, N-borylated 2,5-diarylpyrroles. A gear like dual structural motion in the excited state is responsible for their large Stokes shifts.
在新型氨基硼烷、N-硼酰化 2,5-二芳基吡咯中,扭曲分子内电荷转移(TICT)态发射的荧光发生了明显的红移,并达到了很高的荧光量子产率。激发态中类似齿轮的双重结构运动是它们产生巨大斯托克斯位移的原因。
