[post_content] => Dear All,
The Vice Chancellor's office invites you to a colloquium on "Alkali- and Alkaline Earth Metal Complexes as Catalysts for Sustainable Polymers" by Prof. V. Chandrasekhar, Visiting Distinguished Professor, TIFR, Hyderabad
Abstract: Efficient polymerization methods for the preparation of sustainable polymers such as poly (lactic acid) or poly (ε-caprolactone) and the corresponding co-polymers are important targets of research. In this context, unsymmetrical imino芒鈥濃偓phosphanamidinate, N-P-N ligands (Figure) were designed and synthesized, and their reactivity with various metal precursors was studied. In general, such reactions proceed to afford a monoanionic chelating N-P-N motif that can bind to metal centres affording four-membered rings1-4 (Figure). Utilizing this strategy we prepared a Cs(I) complex2 and a Mg(II) complex4 which were studied by NMR and crystallography. Further, these complexes were shown to be highly efficient catalysts for the homopolymerization of lactide and ε-caprolactone as well for the block co-polymerization of lactide with caprolactone.2,4 These results will be presented.

About the Speaker: Prof V. Chandrasekhar studied chemistry and obtained his PhD degree in 1982 from the Indian Institute of Science, Bangalore and postdoctoral work at the University of Massachusetts, Amherst, Massachusetts, USA. After briefly working at the Research and Development section of the Indian Petrochemicals Corporation at Vadodara, as a Senior Research Officer, he joined the Department of Chemistry at the Indian Institute of Technology Kanpur in 1987 where he has been a full professor since 1995 until his superannuation in November 2023. He served for an additional month at IIT Kanpur as a professor. He served as the Head of the Department of Chemistry, IIT Kanpur (2008–10), and as the Dean of Faculty Affairs, IIT Kanpur (2011–12). He also worked at the Tata Institute of Fundamental Research, Centre for Interdisciplinary Sciences, Hyderabad, as a Senior Professor/Dean (2012–14) and Director (2014–17), National Institute of Science Education and Research (NISER), Bhubaneswar, India, as a Centre Director of the Tata Institute of Fundamental Research, Hyderabad (2017-23). He is currently a visiting Distinguished Professor at the Tata Institute of Fundamental Research Hyderabad. His research interests are in molecular materials, inorganic rings and polymers, main-group organometallic chemistry and polynuclear metal assemblies. He has been a recipient of the S. S. Bhatnagar Award of the Council and Scientific Industrial Research, India, and the Friedrich-Wilhelm-Bessel Research Award of the Alexander von Humboldt Foundation, Germany (With Prof. H. W. Roesky at Goettingen 2003 Dec-2004 June).
He is an elected Fellow of the Indian Academy of Sciences, Bangalore, the National Academy of Sciences, Allahabad, the Indian National Science Academy, New Delhi and the World Academy of Sciences, Trieste, Italy. He is currently the President of the Chemical Research Society of India and the President-elect of the Asian Chemical Editorial Society. He has been on the editorial board of several journals including, Organometallics. Currently he is on the editorial board of Dalton Transactions as an Associate Editor. His research work is documented in 460+ publications.
We look forward to your active participation.
