A Themed Issue in Honor of Late Professor Samiran Mitra

Dear Colleagues,

Magnetochemistry is pleased to announce a memorial Special Issue, dedicated to Professor Samiran Mitra at Jadavpur University, India, on the occasion of his passing away in December 2017, for his outstanding contribution in the research fields of inorganic, coordination, and solid-state chemistry.

Short biography

Dr. Samiran Mitra was born on 28^th of March 1949 in West Bengal, India. He obtained his Ph.D. in inorganic chemistry in 1976 from the Indian Association for the Cultivation of Science. He was a JSPS post-doctoral fellow in the Department of Chemistry, Kanazawa University, Japan (1978-1979) and also worked as a guest scientist in Kernforschungszentrum, Karlsruhe, Germany (1980-1981). He joined Department of Chemistry, Manipur University in India as an assistant professor in 1984 and worked as a guest professor of chemistry at the Univerisity of Kassel, Germany (1990-1991). He moved to Jadavpur University, Kolkata, India as a reader in 1992 and continued his research career there till 2016 as a Professor and Emeritus Professor. In his prolonged research career he received Prof. Priyadaranjan Ray Memorial Award from the Indian Chemical Society in 2006. He supervised the PhD theses of 33 scholars and published 234 scientific articles in peer reviewed journals.

His research interest was focused on the development of the techniques for the synthesis of new multinuclear complexes (homo- or heterometallic) of transition, non-transition, and inner-transition metal ions possessing fascinating architectures. Various Schiff base chelators and bridging co-ligands were used to design such complexes aiming at increasing the molecularity and dimensionality of the complexes utilizing the covalent and weak interactions. The characterizations were performed using various physico-chemical techniques like elemental analyses, UV-Vis, IR, NMR, Mass, EPR spectroscopies, and electrochemical and thermogravimetric analysis. The structures of the synthesized complexes were established by single-crystal X-ray diffraction studies. Variable temperature magnetic susceptibility measurements were performed in relevant cases. Magneto-structural correlations, along with the DFT calculations, were carried out to establish the probable pathways for the exchange magnetic interactions. His research also diversified to the photophysical properties (fluoroscence, as well as photoluminescence), biological activities of the complexes for DNA binding, cleavage studies, and cell inhibitory effect in vitro and in the field of catalysis. The catalase and catecholase mimetic activities of the complexes were investigated with gas volummetry and spectroscopic methods. The transition metal Schiff base complexes were tested as catalysts in various organic transformations such as asymmetric epoxidation of olefins, epoxide ring opening, selective oxygen binding, cycloalkane oxidation, and alkene oxidation in the phase transfer condition, etc.

The main aim of this Special Issue is to publish any research results or a review dealing with any area of magnetochemistry and/or any research subject connected with Prof. Mitra’s research interests.
