Objectives & Goals:
Research in our group focuses on modular and tunable organic donor-acceptor systems in the development of adaptive photofunctional materials, such as dual light emitters, phosphorescence switches and responsive emitters. For this purpose, we utilize synthetic organic chemistry in conjunction with advanced spectroscopic methods and computational calculations.
Our interest in delayed emission of organic light emitters has driven us to the development of new donor-acceptor materials that can show both TADF and RTP. These novel systems are expected to form the basis of singlet and triplet harvesting that can be used in high energy-efficient OLEDs, security-imaging, sensors, sensitizers, photocatalysis to bio-imaging. In this regard, the group is also developing ultra-rigid multiple-donors-acceptor (D2-A/D1D2-A/D4-A) materials that can show high efficiency in OLEDs.
