Extending BN/C=C Isosterism for Developing Novel Functional Materials


Title : Extending BN/C=C Isosterism for Developing Novel Functional Materials.
Speaker : Prof. P. Thilagar, Department of Inorganic and Physical Chemistry, IISc Bangalore.

Abstract:  There has been a great deal of resurgence in boron chemistry in recent years. Substitution of isoelectronic B–N units for C=C units produce molecules with structural similarities to the all-carbon frameworks but with fundamentally altered electronic and optical properties. Ever since the revolutionary work of Dewar nearly sixty  years ago, the liaison between B–N and C–C has attracted attention of organic, inorganic, materials, and computational chemists alike, in recent years. New applications and novel molecular scaffolds resulted from these studies. Recently, our group pioneered the concept of controlling the optical characteristics of luminescent compounds by constraining the molecular conformations. As a result of systematic investigations, very significant advances have been made in our understanding of the solid-state  optical properties of several  BN-compounds.  In this talk, some quite interesting aspects of delayed fluorescence of BN compounds will be presented.

Bio-Sketch: P. Thilagar obtained his B.Sc. from Tagore Arts College and M.Sc from Pondicherry Central University. He received his Ph.D. in 2007 working with Prof. V. Chandrasekhar at the Indian Institute of Technology Kanpur (IIT-K) and has postdoctoral experience from working at the University of Rutgers with Prof. Frieder Jakle. In 2009, he joined the Indian Institute of Science as a faculty member in the Department of Inorganic and Physical Chemistry. In 2009 he was elected as Young Associate of the Indian Academy of Sciences and was the recipient of the CRSI (Chemical Research Society of India) BRONZE medal in Chemistry (2017). He serves in the Editorial Advisory Board of Organometallics journal published by the American Chemical Society. He also serves in the International Editorial Board of Aggregates and Chemphotochem, the journals published by the Wiley vch. His current research interests concentrate on the development and possible applications of various classes of boron-containing luminescent dyes and the medicinal aspects of boron-containing peptides.
