Summary of the new project “Synthesis, characterization, reactivity and catalytic aspects of vanadium complexes” sponsored by SERB

The vanadate-dependent-haloperoxidase enzymes (VHPO) and the covalent bonding of the imidazole moiety of histidine residue through Nɛ to vanadate in the active site stimulated the design of structural models. The chemistry of the vanadium is demonstrated by oxidation states V(IVV) and V(V) which are associated with a variety of cores such as [VO]2+, [VO]3+, [VO2]+, [V2O3]n+ (n = 2, 3, 4), [V2O4]2+, emphasizing the influence of the reaction conditions like the nature of ligands, type of solvents, pH of the reaction medium etc.

Major objectives of the proposed research programme are the development of methodologies to prepare oxidovanadium(IV), oxidovanadium(V), dioxidovanadium(V) and oxidoperoxidovanadium(V) complexes with the chelating ligands having O, N and/ or S donor atoms, characterization of these complexes by various physico-chemical methods including single crystal X-ray study and generation / isolation of intermediate species proposed for haloperoxidases and their characterization by UV-vis, EPR and 51V NMR. Investigation of the property and reactivity of the isolated complexes would provide understanding of the chemistry of vanadium related to the biological systems. Catalytic activity of complexes would provide knowledge on the catalytic ability of the vanadium complexes. Further, the identification of the active species involved during catalytic action would help in proposing suitable reaction mechanism for the catalytic actions shown by these complexes.

Summary of the new project “Dearomatization of Phenols into Benzoquinone Derivatives: Rapid Access to Bicyclo[2.2.2]octenones, Phenoxazines and other Heterocyclic Systems”sponsored by SERB

The project is aimed at the synthesis of novel bicyclo[2.2.2]octenone derivatives via Diels–Alder reaction of benzoquinone monoketals generated in situ by hypervalent iodine reagents mediated oxidation of the corresponding guaiacol derivatives. Another objective is to generate o-benzoquinone monoimides with hypervalent iodine reagents and Michael-type addition of o-aminophenols to produce phenoxazine derivatives. The in situ generated o-benzoquinone monoimides will also be treated with o-phenylenediamines and o-aminothiopehnols to synthesize phenazine derivatives and phenthiazine derivatives. This protocol will be tested for the synthesis of various biologically active phenoxazine derivatives including bezerramycins A–C, chadrananimycin D, grixazones A and B, questiomycin A, and glucosylquestiomycin.

Summary of the new project “Organic materials containing heterocyclic building blocks”sponsored by CSIR

Synthesis and characterization of a series of organic materials featuring fused-ring heteroaromatic donors and π-linkers are proposed. The chromophores such as 10,11-dihydro-9H-thieno[3'',2'':3',4']cyclopenta[1',2':4,5]thieno[3,2-b]thieno[3'',2'':3',4']-cyclopenta[1',2':4,5]thieno[2,3-d]pyrrole, 1H-dithieno[3',2':3,4;2'',3'':5,6]benzo[1,2-d]imidazole and the other linkers proposed in this work remain unexplored. Rigid rod-like materials developed using these building blocks are expected to display unique photophysical and electrochemical properties suitable for their application in electronic devices such as photovoltaics and organic light-emitting diodes. By varying the acceptor strength and the nature of the conjugating linker, it is hypothesized to arrive at dyes showing intense red-shifted absorption properties. In view of significant interest in the development of conjugated materials possessing excellent acceptor properties to replace the fullerene acceptors (PCBM derivatives) widely used in bulk heterojunction solar cells, we also intend to prepare naphthalimide-based derivatives featuring the newly developed heteroaromatic linkers possessing moderate electron-withdrawing capability. These materials are expected to function effectively as electron acceptors in hetero-junction solar cells.

Summary of the new project“Development of fluorescence based selective chemical sensor for Magnesium ion under physiological condition” sponsored by SERB

In order to understand cell physiology,selective detection of biologically importantcations such as Na+, K+, Mg2+, and Ca2+isextremely important. It is important to monitor the Mg2+ ion concentration in the living cells as well as its distribution in subcellular area.So far, there are only few reports of Mg2+-responsive fluorescent probes based on bidentate, tridentate and tetradentate ligands. However, these probes have suffered from one of two major shortcomings, which are low dissociation constant or poor fluorescence response in aqueous medium. Thus the finding of selective Mg2+ sensor at physiological condition remains challenging.

Synthesis and characterization of novel ruthenium nitrosyl complexes and their biological activity studies


There has been considerable current interest in studies on the interaction of nitric oxide (NO) with transition-metal complexes. In 1998 Nobel prize was given for the research in NO.  Nitric oxide, a diatomic radical species, is an important signaling molecule in a variety of biological processes such as vasodilatation, immune response, neurotransmission, apoptosis, etc. in different cells and tissues. In biosystems, NO is synthesized by nitric oxide synthase (NOS) enzyme and several concentration-dependent activities of NO were discovered. Hence, a particular amount of and target specific delivery of nitric oxide and scavenging of nitric oxide by transition-metal complexes are important areas in chemical research. Complexes which could deliver NO upon illumination with light are important for photodynamic therapy (PDT). We are trying to synthesize such molecules which would be useful for PDT.

Theory and Mechanism of Polymer Melt Dynamics: In this proposal we propose a many chain formulation for the dynamics of entangled polymer systems. First the mechanism of anomalous dynamics of entangled polymer melts will be explored by thorough analysis of united atom molecular dynamics (UA-MD) simulation trajectories in the light of the fact that polymer liquids are dynamically heterogeneous even far from their glass transition, due to the interplay between excluded-volume interactions and chain connectivity. With the insights from this study a microscopic theory of entangled polymer melts will be developed based on the Generalized Langevin Equation for cooperative dynamics that includes entanglement points as additional slow variables. Finally the dynamics from the resulting theory will be tested with UA-MD simulation data for entangled melts, specifically the scaling of transport coefficients with molecular weight.

Metal ion assisted artificial base pairing: an alternative approach for the nucleic acid templated chemistry: Introduction of metal ion in the artificial base pairing can be used in absentia of the natural nucleic acid base pairings in the double helical structure of the nucleic acids. The newly joined Ph.D. student in the PI’s group has started working on this project from January 2015. He has already synthesized some of the starting materials required for this project. We bought some DNAs for the study of nucleic acid templated chemistry. In the next step, the modifications of those DNAs with our probe are essential to study the effect of metal ion in the mismatch base pairing.




  • Synthesis and Analytical Application of Polydentate Macrocycles as Chemical Sensor. PI: A. K. Singh (DRDO).


The two chromium chelates of Schiff bases, N-(acetoacetanilide)-1,2-diaminoethane (L1) and N,N´-bis(acetoacetanilide)-triethylenetetraammine (L2), have been synthesized and explored as neutral ionophores for preparing PVC based membrane sensors selective to Cr (III). The addition of lipophilic anion excluder (NaTPB) and various plasticizers viz. o-NPOE, DOP, DBP, TEHP, and BA have found to improve the performance of the sensors. The best performance was obtained for the membrane sensor having a composition of L1: PVC: DBP: NaTPB in the ratio 5:150:250:3 (w/w). The sensor exhibits Nernstian response in the concentration range 8.9 *10-8 – 1.0 *10-1 M Cr3+ with limit of detection 5.6 *10-8 M. The proposed sensor manifest advantages of relatively fast response (10s) and good selectivity over some alkali, alkaline earth, transition and heavy metal ions. The selectivity behavior of the proposed electrode revealed a considerable improvement as compared to the best previously PVC-membrane electrode for chromium (III) ion. The potentiometric response of the proposed sensor was independent of pH of the test solution in the range of 2.0-7.0. The sensor has found to work satisfactorily in partially non-aqueous media up to 20% (v/v) content of methanol, ethanol and acetonitrile and could be used for a period of 3 months. The proposed electrode was used as an indicator electrode in potentiometric titration of chromium ion with EDTA and in direct determination in different water and food samples.
