Research: In IAP, University of Bern, my current aim is to explore the charge transfer characteristics of Nonlinear Optical (NLO) crystals and polymers. The strength of the charge transfer can be tailored choosing suitable donor and acceptor groups. Introduction of dipolar chromophores in the backbone of the polymers as side or main chain constituent can also bring in significant changes. I would be addressing to the questions regarding the equilibrium geometry, bonding features and their dynamics, inter/intra-molecular hydrogen bonding. For the experimental part of investigation, Terahertz spectroscopy, transient absorption and time-dependant Raman spectroscopy will be applied. Density Functional Theory (DFT) calculations will also be performed to analyze the energy gaps for the charge transfer processes besides prediction of the optimized geometries, intra/inter-molecular H-bonding, IR/Raman bands and hyperpolarizabilities.
Another field of my interest is the charge transfer reaction in deep eutectic solvents. The high viscosity and density of these classes of solvents render them unique properties. For example, they can be an alternative solvent to water for chemical reactions. Plants in drought or frozen zones are believed to make use of these classes of solvents and thus drive towards more fundamental investigations.
