Introduction
My research work revolves around understanding dynamical processes like rotational diffusion and photoisomerization in microheterogenous systems. I am currently investigating these dynamical processes specifically in block copolymer reverse micelles. I plan to extend this work in ionic liquids as well as systems comprising ionic liquids.

Article
Fluorescence anisotropies of a nonpolar solute, 9-phenylanthracene (9-PA), have been measured in 1-alkyl-3- methylimidazolium (alkyl = methyl, butyl, octyl, and dodecyl) bis(trifluoromethylsulfonyl)imides ([RMIM][Tf2N]) with varying amounts (0−0.3 mole fraction) of lithium bis(trifluoromethylsulfonyl)imide (LiTf2N). This study has been carried out...

Rotational dynamics of 1-alkyl-3-methylimidazolium-based ionic liquids has been investigated by monitoring their inherent fluorescence with the intent to unravel the characteristics of the emitting species. For this purpose, temperature-dependent fluorescence anisotropies of 1-alkyl-3-methylimidazolium (alkyl = ethyl and hexyl) ionic liquids with a...

Solute dynamics has been explored in reverse micelles formed with the triblock copolymer (EO)13–(PO)30–(EO)13 (L64), where EO and PO represent ethylene oxide and propylene oxide units, respectively, with small amounts of water in p-xylene. To this effect, nonradiative rate constants (k_nr ) and reorientation times (tau_r ) of two carbocyanine deriv...

Rotational diffusion of two structurally similar organic solutes, 9-phenylanthracene (9-PA) and rhodamine 110 (R110) has been investigated in 1-methyl-3-octylimidazolium tetrafluoroborate–diethylene glycol ([MOIM][BF4]–DEG) mixtures to understand the influence of organic solvent on the organized structure of the ionic liquid. The reorientation time...
Article
Rotational diffusion of two structurally similar nonpolar and charged solutes has been examined in mixtures of an ionic liquid and an organic solvent of comparable size and viscosity with an intent to find out whether the organized structure of the former influences solute rotation. To this effect, temperature-dependent fluorescence anisotropies of...
