摘要

我们探索了推拉二苯乙烯类化合物 4,4'-二甲氨基硝基苯乙烯 (DNS) 的激发态动力学，它经历了扭曲的分子内电荷转移和/或反式到顺式异构化，而这取决于溶剂的极性。我们展示了飞秒泵/宽带探针数据的全局分析如何帮助阐明相互转化的构象和/或异构体的参与，这些构象和/或异构体通常在单波长动力学分析中未被探索。

Dielectric-Controlled Ultrafast Twisted Intramolecular Charge-Transfer VS trans to cis Isomerization Pathways in a Push-Pull Stilbene: Global Analysis Perspectives

We explore excited-state dynamics of 4,4’-dimethylaminonitrostilbene (DNS), a push-pull stilbene, undergoing twisted intramolecular charge transfer and/or trans to cis isomerization, which is dependent on solvent polarity. We show how global analysis of femtosecond pump/broadband-probe data aids in elucidating the involvement of interconverting conformers and/or isomers, and the timescales associated with such interconversion, often unexplored in single-wavelength kinetic analysis.
