Project R-16115

Title

Organic opto-electronic devices for the generation and detection of circularly polarized light (Research)

Abstract

Chiral organic semiconductors hold immense potential for nextgeneration optoelectronic devices by leveraging chirality to manipulate circularly polarized (CP) light. However, translating material-level chirality into efficient device-level functionality remains a challenge. This project focuses on understanding and optimizing chirality transfer from chiral dopants to achiral polymer semiconductors, where post-processing induces supramolecular helical ordering of polymer chains. Precise control of chirality transfer in advanced polymer systems, including efficient emitters and low bandgap materials, will enable CP-responsive electronic devices with unprecedented performance. This project will investigate chirality transfer mechanisms using advanced chiroptical spectroscopy and theoretical modelling, correlate structural chirality with charge transport properties, and engineer device architectures for CP light emission and detection realizing organic CP-light emitting diodes and CP-photodetectors. By integrating innovative material design, spectroscopy, and device optimization, this project bridges fundamental research with application. Expected outcomes include insights into chirality transfer, pioneering CP device performance, and new design principles for chiral optoelectronic polymers, positioning them as key enablers for sustainable displays, optical computing and advanced biomedical imaging applications.
