Present research topics:
(i) Ultrafast electron and proton transfer, and electronic energy transfer dynamics in confined environments of ionic liquids and deep eutectic solvents.
(ii) Effect of solvation on chemical reaction dynamics in bulk and confined environments of ionic liquids and deep eutectic solvents using ultrafast fluorescence spectroscopy.
The main objective of this project is to understand the molecular level properties of ionic liquids and deep eutectic solvents in various confined environments and how they differ from corresponding bulk environments. Steady state and time-resolved fluorescence spectroscopy will be used as the primary experimental techniques. Photo-induced proton and electron transfer reactions of some solutes will be carried out and kinetics of various rate processes will be investigated. Excitation wavelength dependent electronic energy transfer between donor and acceptor molecules will be conducted to investigate the local properties and interaction of the confined media. Non-reactive solute will be used in these media to study the dynamics of solvents and subsequently the influence of solvation on photo-induced processes will be determined.
