Hello, I'm Mithu Roy

Mithu Roy presently working as a research scholar in the Department of Chemistry at Indian Institute of Technology Guwahati, India. He received his B. Sc. degree in chemistry from Surya Sen Mahavidyalaya under the University of North Bengal, West Bengal in 2017. Then he moved to Indian Institute of Technology Indore to pursue his master’s degree. During his M. Sc. Project work on Organic chemistry he developed keen interest towards research and development. His passion for research and curiosity to learn more about organic transformations and their mechanisms led him to choose research as career and to follow that passion he joined the doctoral degree in IIT Guwahati as a research scholar under the supervision of Dr. Dipankar Srimani in December 2019. He got awarded with the prestigious Prime Minister’s Research Fellowship (PMRF) award in January 2021.

In recent years, Photo Redox Catalysis has emerged as one of the hottest research areas in organic chemistry. It is a branch of photochemistry that employs single electron transfer (SET) processes. Three kinds of photo redox catalyst are used generally, transition metal-based complexes, organic dyes, and semiconductors. In photo redox catalysis upon irradiation with visible light, catalysts get excited into higher energy levels and take part in SET processes with the reacting substrate and facilitate the reaction by generating a free radical. Further, the photocatalyst goes back to the lower energy ground state and is ready for a new catalytic cycle. Ruthenium and iridium-based polypyridyl complexes are the most widely used photo redox catalyst due to their high photocatalytic activity. Since these are highly expensive and toxic in nature, scientists are finding their replaceable counterparts. The organic photo redox catalysts are the most reliable counterpart of the transition metal chromophores.

Our main focus is on the transition metal-free organic photo redox catalysts, as they are less toxic, cheaper, and readily available. The common organic photo redox catalysts are organic dye molecules like Eosin Y, Rose Bengal, Rhodamine 6G, etc.

Our present research interest is on organic photo redox catalysis C-C, C-X (X= Heteroatom) bond formation, C-H bond activation and cross dehydrogenative coupling reactions.

Research Interests

  • Organic Photo Redox Catalysis.
  • Transition Metal Photo Redox Catalysis.
  • Dual Photo Redox Catalysis
