Research Interests

Our research goals involve (1) bottom-up synthesis of atomically precise, structurally well-defined enantiopure chiral nanocarbon materials (2) to use in-depth time-resolved spectroscopic investigations to get insight into the structure–property relationship, analyze effects that arise from the marriage of chirality and optoelectronic properties, (3) electron microscopic analysis to study their self-assembly behavior, and (4) explore the potential of these nano-structures for applications in organic electronics and investigate physical phenomena namely chirality induced spin selectivity and magneto-chiral anisotropy in a quest to develop multifunctional spintronics devices.

Methods and Techniques

Interdisciplinary nature our research activities requires learning and utilization of variety of spectroscopic-techniques and instrumentations. Synthetic organic chemistry. Spectroscopic techniques—1D and 2D NMR, EPR, UV-vis (absorption/emission), IR, Raman, CD and CPL. Mass spectrometry. Cyclic voltammetry and Spectroelectrochemistry. Microscopic techniques—AFM, SEM, STEM and TEM. DFT calculations.

CV of Dr. Prince Ravat

Since 2018 Research Group Leader, Institute of Organic Chemistry & Center for Nanosystems Chemistry, University of Würzburg, Germany
2017-2018 JSPS Research Fellow, University of Tokyo, Japan
2014-2017 Postdoctoral Research Associate, University of Basel, Switzerland
2011-2014 Dr. rer. nat. (Physical Organic Chemistry), Max Planck Institute for Polymer Research, Mainz, Germany

Backround and Motivation

Our objective is to harvest the additional—functionalities namely circular dichroism and circularly polarized luminescence and—physical phenomena such as chirality induced spin selectivity and magnetochiral anisotropy, which chirality brings in chiral-organic-molecules and translate them into further advancement of organic electronics devices.
