Ultrafast charge transfer dynamics in excited-state donor-acceptor benzylideneaniline.

ABSTRACT: Imine-based molecular systems have served as promising semi-conductive materials for applications in light-emitting diodes and photovoltaics. Benzylideneaniline, an imine-based molecular system, acts as a bioisostere of diarylethylenes such as stilbene and resveratrol, and plays a crucial role in pharmaceutical and biological applications. However, the excited-state dynamics of benzylideneanilines is less explored. In this context, we investigated 4'-(dimethylamino)benzylidene-4-nitroaniline (DMABNA), an imine-based donor-acceptor system, to unravel the excited-state dynamics. Here, we explored excited-state charge transfer dynamics and associated structural dynamics in various solvent environments through femtosecond transient absorption (fs-TA) and femtosecond fluorescence spectroscopic
