About us

Ray’s research group specializes in modular organic donor-acceptor conjugate acid-base pairs. Their work advances the development of triplet energy harvesting and adaptive materials for applications in OLEDs, sensitizers, data security, and sensors. The group employs synthetic organic chemistry, advanced spectroscopic tools, and quantum studies to achieve their goals.

A key area of focus for Ray’s team is controlling molecular conformation to achieve dual emission with triplet harvesting. This research is paving the way for significant advancements in white display technology.

In their work on thermally activated delayed fluorescence (TADF) and room temperature phosphorescence (RTP) switches, the group is making strides in data security, solar energy conversion, and memory devices. These innovations have the potential to revolutionize multiple high-tech industries.

Using a supramolecular approach, the team is exploring triplet-active 3D-cages. These systems show great promise for applications in sensing, as well as in sensitizer and photocatalysis technologies. This research represents a significant step forward in the field of advanced materials science.

The group is also developing visible-light-absorbing photocatalytic systems. These systems are designed to harness triplet energy effectively, expanding the potential for sustainable energy solutions.


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.
