Research Overview

Ray's research group explores innovative organic donor-acceptor conjugates to advance energy harvesting and adaptive materials for OLEDs, data security, and sensors. By leveraging synthetic chemistry, spectroscopic tools, and quantum calculations, they control molecular conformation and aggregation. This focus leads to photophysical properties such as white light emission, triplet harvesting, and multi-photon processes. Their work produces materials with bright potential for future WOLEDs, photon conversion, and energy devices. They also create emitters as photo-switches for data security, solar storage, and memory. Extending their research into macrocyclic systems opens new paths in sensing and photocatalysis, pushing forward advancements in material science. Know more: Click here
