Abstract

4,6 Dinitroresorcinol undergo reduction with alcoholic alkali to form a new Azo polymer Poly[Azo(1-napthol)] These Co-ordination polymers Poly azo chelates were prepared with Cu+2, Ni+2, Co+2, Mn+2 and Zn+2 Metal ions. The newly polymer synthesised at scheme-1 shown in Figure-1 were characterized by various spectral techniques. The polychelates reported in this study were coloured solids and practically insoluble in water and in regular organic solvents. We have characterized with elemental analysis, molar magnetic susceptibilities, spectroscopic (IR & Reflactance) data and Thermogravimetric analysis. Nonaqueous conductometric titrations were used to determine the number average molecular weight of the compound. Room temperature conductivity data for ligand and its polychelates indicated that the electrical conductivity of these compounds lie in the semi-conducting range (1.33x10-8 to 8.20x10-11cm-1). The log vs 1/T plots were found to be linear, which also indicated the semiconducting behavior of the ligand and the polychelates in the temperature range studied. The general conduction behaviour of the electrical conductivity ( ) can be described by = 0 exp (-Ea/kT), where 0 is a constant, Ea the activation energy of the conduction process. The magnitude depends on T the absolute temperature and where K is the Boltzman constant. Activation energy (Ea) Az-ligand (Polymer) The Azo polymer (Az),poly[azo(1-napthol)] and poly chelates is derived from the slope of plots with values from 0.60 – 1.78 eV and they are shown to follow this order Az-Cu+2>Az-Mn+2>Az-lig>Az-Co+2>Az-Zn+2>Az-Ni+2.
