Physico-Chemical Characterization And
Ionic LiquidLiquid----SupportedSupported Schiff Bases and their Transition Metal Complexes: Synthesis, PhysicoPhysico----ChemicalChemical Characterization and Biological Activities A Thesis submitted to the UNIVERSITY OF NORTH BENGAL For the Award of DOCTOR OF PHILOSOPHY ininin CHEMISTRY ByByBy Mr. SANJOY SAHA M.Sc. in Chemistry Supervisor DR. BISWAJIT SINHA DEPARTMENT OF CHEMISTRY UNIVERSITY OF NORTH BENGAL OCTOBER-2018 Dedicated To My Beloved Parents Abstract Chapter I contains a brief overview on the ionic liquids (ILs), specially functionalized ionic liquids (FILs) along with the properties of the ionic liquids consisting of different cations and anions, their applications and the advantages of using ILs over conventional organic solvents. Chemistry of Schiff bases and their transition metal complexes as well as their applications in different fields were also briefly discussed. This chapter also contains a brief literature survey on related works as well as the object and application of the research works embodied in this dissertation. Chapter II briefly describes the spectroscopic and analytical techniques employed for the physico-chemical characterization of the synthesized compounds. This chapter also contains sources of the different chemicals used and describes the syntheses and physicochemical characterization of some amine functionalized ionic liquids required for the syntheses of various ionic liquid-supported Schiff bases used as ligands in subsequent chapters of this thesis. In chapter III Mn(II) and Co(II) complexes synthesized from the ionic liquid- supported Schiff base, 1-{2-(2-hydroxybenzylideneamino)ethyl}-3-methyl imidazolium bromide have been presented. Their structural characterization by various analytical and spectroscopic methods was described. Their antibacterial activities were tested by in vitro disc diffusion method against Escherichia coli and Bacillus subtilis to assess their minimum inhibition concentrations. -

Co(II), Ni(II) and Cu(II) complexes of an ionic liquid-supported Schiff base 1-{2-[(2-hydroxy-5- bromobenzylidene)amino]ethyl}-3-ethylimidazolium tetrafluoroborate were synthesized and characterized by various analytical and spectroscopic methods such as elemental analysis, UV-Visible, FT-IR,1H NMR, ESI MS, molar conductance and magnetic susceptibility measurements. Based on the spectral studies, tetra coordinated geometry was proposed for the complexes and molar conductance of the complexes revealed their electrolytic nature. The synthesized Schiff base and its complexes were evaluated for in vitro antibacterial activities against Gram positive and Gram negative bacteria. The complexes along with the Schiff base showed very significant biological activity against the tested bacteria. Keywords.
