Photoprocesses of excited molecules in confined liquid environments: an overview

Abstract

The photoprocesses like excited state proton transfer (ESPT), intramolecular charge transfer (ICT), fluorescence energy transfer (FET), occurring in the excited molecules find ample applications in the chemical and biochemical fields. These photoprocesses are markedly affected by the introduction of biomimicking liquid confining environments like micelles, reverse micelles, cyclodextrins, proteins, etc. The local polarity, viscosity and pH, induced by the confined environments have a significant role in modifying the photoprocesses. In this review we have presented a comprehensive report of the recent progress in the study of these photoprocesses in photoexcited molecules in different confined liquid environments. Mostly, recent works have been reviewed in this article to acquire information about progress in the photophysical and photochemical reactions in different confined environments.
