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.

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.
