We are mainly interested in the photophysical behavior of electron donor-acceptor (EDA) molecules in both conventional solvents and in room temperature ionic liquids. We are interested to study important photo-processes such as electron transfer, proton transfer reactions etc. of different EDA molecules by examining the spectral and temporal behavior of the systems using steady state and time-resolved absorption and fluorescence techniques.
We are interested to study the solvation dynamics in room temperature ionic liquids. We are interested to investigate the spectroscopic and microscopic properties of fluorescent organic nanoparticles grown in ionic liquid microemulsions. We are also interested in the design and development of molecular and material (MCM-41) based systems that are capable of sensing various biologically and environmentally important metal ions and anions. The sensing event is achieved by monitoring the fluorescence response of the system in absence and presence of analytes of interest.
Single crystal X-ray diffraction studies and quantum chemical calculations are also used as the valuable adjunct to our current research.
