Abstract

In this contribution we present new experimental and theoretical results for the intramolecular charge transfer (ICT) reaction underlying the dual fluorescence of 4-(dimethylamino)benzonitrile (DMABN), which indicate that the fully twisted ICT (TICT) state is responsible for the time-resolved transient absorption spectrum while a distinct partially twisted ICT (pTICT) structure is suggested for the fluorescent ICT state.

摘要

在本贡献中，我们呈现了 4-(二甲基氨基)苯甲腈 (DMABN) 双荧光的分子内电荷转移 (ICT) 反应的新实验和理论结果，这些结果表明完全扭曲的 ICT (TICT) 态负责时间分辨瞬态吸收光谱，而荧光 ICT 态则存在明显的部分扭曲 ICT (pTICT) 结构。
