“…If the reaction was carried out under more dilute conditions (samples 4, 8, and 9), the yield sharply decreased. We previously reported26, 27 this phenomena of catalysis with copper, nickel, and cobalt for other derivatives of polyaniline, such as poly(aminophenols), poly(diamines), and poly(amino acids).…”

Poly(m-aminophenyl acetic acid) was synthesized under different conditions from the respective monomer, using ammonium persulfate as oxidizing agent in both the presence and the absence of CuCl 2 in HCl(aq). Moreover, the copolymers between aniline and m-aminophenyl acetic acid were prepared at several feed mol ratios (f 1 ) of aniline. Copper was introduced by the Batch method in the homo-and copolymers of different compositions. The polymers were characterized by FTIR and UV-vis spectroscopy, elemental analysis, thermal analysis, and electrical conductivity. The thermal stability and the content of copper increased as the content of aniline was increased in the copolymers. Moreover, the copolymers showed a high thermal stability; at 400°C a weight loss Ͻ 10% was observed. The electrical conductivity was increased with a higher content of aniline in the copolymers, achieving semiconduction values.

“…Doping has also been achieved by using Lewis acids such as SnCl 4 , GaCl 3 , AlCl 3 , FeCl 3 , CuCl 2 and EuCl 3 . In recent years, the doping of PANI with transition metal ions has attracted more and more research interest owing to the distinctive electron exchange property of the combination, higher specific capacitance values and thermal stability . Unlike the protonation by Brøsted acids, Lewis acid doping occurs either on the imine nitrogen atoms or both on the imine and amine nitrogen atoms of PANI backbone, depending on the electrode potential of the metal ions, and hence the macromolecular complex forming interactions between PANI and metal ions give rise to novel chemical and physical properties.…”

Polyanilines (PANIs) doped with Zn 2+ and Cu 2+ were synthesized by H 2 O 2 oxidative polymerization of aniline in the presence of corresponding metal chloride in solution. The products were characterized by elemental analysis, UV-Vis-NIR, FTIR and Raman spectroscopies. Scanning electron micrograph was employed to examine the morphology of PANIs fabricated in the presence of different transition metals. Experimental results showed that transition metal ions had been successfully incorporated into the polymer, and there was a strong interaction between the transition metal ions and the PANI chains. The electrical conductivity of PANI doped with Zn 2+ and Cu 2+ is 0.37 and 0.21 S/cm, respectively, which is higher than that of HCl doping PANI corresponding to 0.052 S/cm. The cyclic voltammetric study has indicated that incorporation of metal ions in PANI backbone results in increasing of specific capacitance compared to that of HCl doping PANI.

“…The doping process occurs at imine nitrogen atoms accompanied with an internal redox reaction that results in the formation of semiquinone segments. Additionally, another dopant, such as transition metal,3–6 and alkali metal,7, 8 can also be employed to achieve high conductivity through interaction with nitrogen atoms of polyaniline backbone. The doping mechanisms of EB with metal ions present two interaction formulas on the polymer backbone.…”

The doped polyaniline (PANI) with rare earth ions, which exhibits an increasing conductivity and strongly enhanced fluorescence emission, was prepared by dispersing PANI powder suspension in acetonitrile solution containing rare earth ions according to different mass ratios of rare earth ions to PANI at room temperature. The structure of the doped PANI was characterized by the spectra of FTIR, Raman, UV‐vis, and XRD. Red‐shifted change for the quinoid and benzenoid stretching vibration is observed in IR and Raman spectra after doping rare earth cations, and UV‐vis absorption peak also presents a red‐shift, indicating that the doped PANI possesses a better delocalization of electrons along the mainchain backbone. The experimental data show that the electrical and optical behaviors of PANI strongly depend on the species of rare earth cations and their concentration. It is found that enhancing fluorescence for the doped PANI is observed by comparing with emeraldine base (EB). Moreover, the conductivity of the protonated PANI samples doped with Eu3+, Tb3+, and Y3+ ions, increases from 2.1 × 10−4 to 3.33 S cm−1, 1.50 × 10−1 S cm−1 and 2.26 × 10−1 S cm−1. © 2012 Wiley Periodicals, Inc.
