About us

Ray’s research group focuses on modular organic donor-acceptor-based conjugate Acid-Base pairs in developing triplet energy harvesting and adaptive materials for OLEDs, sensitizer, data security, and sensors. For this purpose, he uses synthetic organic chemistry with advanced spectroscopic tools and quantum studies.

Rays group focuses on controlling molecular conformation has driven them toward realizing dual emission with triplet harvesting. The group is also developing visible-light-absorbing photocatalytic systems based on triplet energy harvesting.

The group also develops TADF/RTP switches for data security, solar energy conversion, and memory devices.

Using a supramolecular approach, triplet active 3D-Macrocyclic systems are also being explored for sensing, and sensitizer/photocatalysis applications.


Ph.D.: The group is looking for motivated candidates with an organic/physical chemistry background. Interested candidates can contact us with their CV. 

Postdoc: The group encourages motivated candidates to apply for postdoctoral positions with NPDF/other fellowships. Interested candidates can directly contact us.

Project/Internship: The group encourages motivated UG/PG students to apply for project/internship positions.
