PREPARATION, CONDUCTIVITY AND MORPHOLOGY BEHAVIOR OF BIS (BIDENTATE) LIGAND AND ITS CHELATE POLYMERS

The present paper describes three chelate polymers of transition metals were synthesized by interaction between suberoyl bis (paramethoxyphenylcarbamide) with metal acetate using dimethylformamide as solvent. The newly synthesized chelate polymers were found colored and insoluble in all common organic solvents. The resulting polymers were characterized by elemental analysis, Fourier Transform Infrared Spectrophotometer (FTIR), X-ray diffractrometric and Thermogravimetric Analysis (TGA). The half decomposition temperature and lattice water of polymers were determined by thermogravimetric analysis. On the basis of above studies, the chelate polymers were found to have tetrahedral geometry. Furthermore, solid state conductivity of all chelate polymers has been measured in compressed pellet form over 311 K and found conductivity in range 6.15 × 10-10 ? 1.8 × 10-5
cm-1 which indicates the semiconductor nature. The crystalline and amorphous natures of metal chelate polymers were determined by X-RD. SEM studies determine surface morphology of polymers. SEM images of these chelate compounds were shown at higher magnification and data reveal that, particle sizes of chelate compounds were found to be micro level. This technique was noteworthy helpful to identify the difference in morphology of chelating ligand and their chelate polymers.
