Green synthesis, characterisation and antibacterial activity studies of new multifunctional nano polymeric material, which may have multidimensional application in water purification

A novel polymeric resin was synthesized by condensing a Schiff base of 6-chloro-2-aminobenzothiazole and salicyldehyde with formaldehyde, which may have multidimensional application. First step of the synthesis of novel polymeric material is synthesis of Schiff base, which is the monomer of the resin. The Schiff base was synthesize by using greener method to reduce hazardous chemical waste and reaction time, so that reduction of environmental pollution and conservation of energy can be achieved. The greener method is compared with the conventional method. The metal polychelates of the polymeric resin with Cu²⁺ and Fe³⁺ were synthesized. The Schiff base, resin and its polychelates were converted to nanodimension and its dimension is measured by DLS method. The structure of the Schiff base, resin and polychelates are ascertained by FTIR, ¹H NMR spectroscopy. The experimental data are compared with the computational data obtained from Gaussian software to ascertain the synthesis of these materials. These materials have a very wide range of application starting from analytical chemistry to biochemistry. The antibacterial activities of Schiff base, resin and metal polychelates were studied against pathogenic bacteria Escherichia coli by turbidity measurement method. All these materials are found to be effective against the tested bacterial species, whereas the polychelates are shown exceptional results.
