“…The trivalent metal ions coordinate with benzoid groups of PANI unit and replenish the activity by two fold for the PANI chain. 37 Here, Ru 3þ is a trivalent metal ion, can bind¯rst with the benzenoid N atom. The interaction between the polymer and the ruthenium salt is schematically shown in Fig.…”

HCl doped polyaniline (PANI) and Ru (III) doped polyaniline (Ru/PANI) have been successfully prepared by in situ oxidative polymerization method and the e®ect of transition metal incorporation in PANI backbone is investigated thoroughly by the execution of Fourier transform infrared spectroscopy (FT-IR) and Raman study. Moreover, to examine the change in surface and bulk morphology of the composites, the¯eld emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) have also been carried out, which revealed the agglomerated state of PANI after being Ru doped. The con¯rmation of the presence of Ru in the composite is achieved by the energy dispersive X-ray spectroscopy (EDS). Also, the electrochemical characterizations namely, cyclic voltammetry (CV), ac impedance spectroscopy (EIS), cyclic chargeÀdischarge (CCD), of the composite was performed by conventional three-electrode system using 1 M H 2 SO 4 electrolyte. On doping with Ru, an increment of speci¯c capacitance of PANI from 160 F/g to 425 F/g has been achieved with a considerable increase in cycle stability.

“…Interactions of PANI with metal ions give rise to novel chemical and physical properties of the formed macromolecular complex. 19 Rare earth-PANI complexes are important in respect to its possible forefront applications in the areas of research as well as industrial applications. 1 POT has the similar structure with PANI; in the same way, interactions of POT with rare-earth ions may bring rise to novel chemical and physical properties of the formed macromolecular complex, and the POT can be used for emitting elements in organic light-emitting devices (OLEDs) and dopant additions to enhance quantum yield in OLEDs, 20 it can also be used as catalyst for some polymer reactions, [21][22] and so on.…”

The poly-o-toluidine (POT) was prepared under different magnetization in solution containing 0.5 mol dm À3 o-toluidine, 1.0 mol dm À3 HCl with and without 0.5 mol dm À3 DyCl 3 , respectively. Their conductivity, UV-vis, FTIR spectra, X-ray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscope (SEM) were investigated. The results of conductivity showed that magnetic field and the cooperative effect of Dy 3þ and magnetic field do obvious effect to conductivity of POT. Meantime, they also can make the energy for the p-p* transitions and quinoid ring transition in UV-vis spectra smaller. At high magnetization the peaks of POT due to QÀ ÀNH þ À ÀB or BÀ ÀNH þ À ÀB and CÀ ÀH out of plane on 1,4-ring or 1,2,4-ring disappeared in FTIR spectra. Magnetic field and Dy 3þ can make three dimensions morphologies of the POT clear, but they scarcely affect the crystallinity of POT.

“…10 Recently, it was reported that PANI could interact with many heavy metal ions [11][12][13] and rare-earth cations. 10,14,15 Because rareearth elements have special electronic properties, viz. their f-f electronic transitions are relatively insensitive to perturbations in their chemical environment, complex formation of organic polymers with lanthanide ions is of particular interest.…”

“…Compared with these techniques, the chemical synthesis of conducting polymer is also of great importance since it is a very feasible route for the mass production. 25 Because the polymer cannot usually form a suitable ligand environment around the lanthanide ion, 10 lots of studies about the rare-earth-organic polymer complexes are needed. According to literature, 26 the existence of paramagnetic ions (for example, RE 3ϩ ) in solutions can greatly increase the effects of magnetic alignment and improve the properties of polymers.…”

Gadolinium Chloride (GdCl 3 ) has been employed as dopant to synthesize conductive polyaniline (PANI) using chemical method. The resulting products were characterized using infrared spectroscopy, UV-vis spectra, scanning electron microscope, differential thermal analyzer, and X-ray diffraction. It was found that Gd 3ϩ can interact with PANI chains and induce changes on the properties of PANI. The addition of GdCl 3 could greatly increase electrical conductivity and crystalline degree of PANI. Changes in UV-vis and FTIR spectra show that there exists interaction between gadolinium ions and PANI chain. The effect of different proportions of ammonium persulfate on the properties of PANI was also discussed. When the molar ratios of GdCl 3 to aniline is 2 : 1 and ammonium persulfate to aniline is 1 : 1, the more uniform and regular PANI nanofiber can be prepared.
