| Abstract: | Poly(m-phenylene diamine) has been synthesized and characterized by physical and spectral techniques. The effect of doping Cr, Co and Ni ions on the spectral, thermal and optical properties has been studied. Optical band gap measurements indicated that, doped polymers have wider optical band gap than the pure one. The effect of doping on the thermal stability differs according to the doped metal ion. The doped with Cr ions poly(m-phenylenediamine) has been used as a precursor of mesoporous Cr2O3 nanoparticles, which have been also characterized by XRD and HR-TEM. |
