Previous Research Works (in India)


The first research experience in the frontier of chemistry was working on the `Synthesis of Ru Based Chiral Bisoxazoline Catalyst (Fig.1.) for Airobic Epoxidation of Olefins' under the supervision of Prof. S. Chandrasekaran, in the Department of Organic Chemistry, IISc, Bangalore as J. N. C. A. S. R. Summer Research Fellow in 2000. Fort this research work, the prestigious Rajiv Gandhi Science Talent Research Fellows - 2000 was awarded.

The next research was at IIT Kanpur for my master's thesis under the supervision of Prof. V. Chandrasekhar on the `New Polymer Supported Catalyst for Phosphate Ester Hydrolysis'(2000-2001).

With the second time opportunity to work as JNCASR Summer Research Fellow at IISc, Bangalore (summer 2001), a new research on the `Synthesis of Cyclodextrine Disulfide Dimers (Fig.3.) With Tetra-thiomolybdate' was carried out under the supervision of Prof. S. Chandrasekaran. The extension of which was working towards the synthesis of new nano-fibers resulting only from the hydrophobic interaction (i.e. The Inclusion Complex) of cyclodextrine dimmers and bulky dipeptide.

With the CSIR fellowship, I came back to IIT Kanpur, to continue my M.S.-thesis work under the supervision of Prof V. Chandasekhar as a Junior Research Fellow (2001-2002). After completing the catalytic studies with the previous Zn complex of cyclophosphazene based pyrazolyle ligand and the RNA model substrate as phosphate ester, a new project was started in modifying the catalytic system by changing the `ligand'. While pursuing so, some new dendrimeric ligand systems based on cyclotriphosphazene (Fig.4.) were synthesized with the pyrazole and the pyrazolyle methane derivatives as donors.


The Current Research works (@ Penn)


    Working for the Ph.D. thesis at Penn under the supervision of Prof. Michael J. Therien.

    Currently the main focus of the research is on `The di-, tri- and tetrameric Cofacial Porphyrin' systems, synthesizing via a metal mediated [2+2+2] cycloaddition reaction, for multy-elctron catalysts, like catalyst for dioxygen reduction to water (4e process). The same synthetic strategy is also being applied to synthesize dioxygen activation catalytic systems as a model of low spin Heme-R state.

    Being associated with the Nano Technology Institute (NTI) another interesting research work on The Spectroscopic Studies and Development of New Suspensions and Separation Techniques for SWCNT's in acqueous medium is under investigation with substantial amount of work done. On that an advanced and interesting work is under investigation with emmisive polymer to understand the binding ability as well as the energy transfer process from the polymeric surfactant to nanotube.
