Abstract

The oxidative polycondensation reaction conditions of E3amino43bromophenyldiazenyl1Hpyrazol5ol Schiff base monomer has been accomplished using NaOCl and air O2 oxidants in an aqueous alkaline medium The optical conductivity dielectric and optical properties of synthesized polySchiff base were examined The magnitude of the refractive index decreases with increasing of photon energy up to about 25 eV then refractive index of the polySchiff base increases with increasing of photon energy The E0 and Ed values of the polySchiff base were found to be 534 and 922 eV respectively An indirect energygap value of the polySchiff base was found to be 094±0009 eV A direct energygap value of the polySchiff base was found to be 138±001 eV and 196±0009 eV at first region and second region respectively Absorption coefficient K changes from 1187 to 1825 cm−1 In addition to fluorescence property of polySchiff base was investigated Finally polySchiff base and Schiff base monomer were tested for antibacterial activities against some bacteria
