Research

Hariharan group focuses on integrated endeavors to synthesize novel and diverse architectures, investigate/regulate the ultrafast processes and understand the theoretical reasons behind these events. Understanding the various weak noncovalent interactions driving elegant crystalline and supramolecular architectures is also our research interest.

PhD Thesis Research supported by Prime Minister's Research Fellowship (PMRF)

I'm pursuing my doctoral research under the guidance of Prof. Mahesh Hariharan. My doctoral research addresses explaining various photophysical phenomena using the concept of excited state aromaticity with the aid of ultrafast spectroscopic techniques and computational methods.

Aromaticity is an engrossing concept extensively used to rationalize various chemical phenomena. For the past few years, the research on the influence of aromatic stabilization and destabilization in excited state phenomena has gained huge scientific attention.. In our quest to unravel the distinct photophysical phenomena exhibited by functional organic chromophores we decided to delve into the field of excited state aromaticity. Exploring the aromaticity of excited states has proven to be an indispensable strategy to comprehend the photoexcited state phenomena/photochemical processes and thereby tune the photophysical properties.

In my research I will be investigating the substantial influence of triplet excited state in functional organic chromophores have on the diverse photoexcited state phenomena including phosphorescence, delayed emission and singlet fission, crucial for the design of organic photovoltaics.

The following points would be addressed in my PhD work:

Explaining various photophysical phenomena using excited state aromaticty
Design strategies for robust photofunctional materials by tuning excited state aromaticity

Other Interest

Attempts to explore ultrafast processes occurring in helical aromatics leading to energy and exciton migration.
