Dr. Jayamurugan Govindasamy

Associate Professor (Scientist-E)

New synthetic methods, Functional organic materials, Supramolecular chemistry, Polymer chemistry. The research in my group is centred on synthetic organic chemistry with a view to exploring nanoporous and nanomaterials for various types of applications ranging from energy, catalysis, sensing, and Nanotherapeutics. Thus, it is highly interdisciplinary in nature. The general strategy of our research is designing and synthesizing the functional nanomaterials with targeted applications and understanding the properties by applying state-of-the-art characterization techniques.

Research Highlights

  • Urea-functionalized 4-ethynylbenzenes under- go facile formal [2 + 2] cycloaddition followed by retroelectrocyclization upon reaction with tetracyanoethylene, yielding 1,1,4,4-tetracyanobuta-1,3-dienes-based push−pull chromophores. Unlike the N,N′-dialkylamino group, urea functionalization provides easy access to further functionalization on these chromophores. The resulting chromophores exhibit unexpected white light emissions apart from various inherent properties like intramolecular charge-transfer band and redox behaviour (more details, please read: J.
