“…Sulfonated self-doped polyaniline has been extensively studied due to its unique electrochemical properties, water solubility, improved processability and potential industrial applications [6][7][8]. PMAS is a fully sulfonated conducting polymer that has been synthesised by chemical and electrochemical polymerisation of 2-methoxyaniline 5-sulfonic acid, MAS [9,10].…”

Immobilisation of a luminescent material on an electrode surface is well known to substantially modulate its photophysical and electrochemical properties. Here a positively charged ruthenium metal complex ([Ru(bpy) 3 ] 2+ ) is immobilised on all electrode surface by ion paring with a sulfonated conducting polymer poly(2-methoxyaniline-5-sulfonic acid), (PMAS). Significantly, our study reveals that the electron transport between the ruthenium metal centres can be greatly enhanced due to the interaction with the conducting polymer when both are surface confined. Charge transfer diffusion rates in the present system are an order of magnitude faster than those found where the metal centre is immobilised within a non-conducting polymeric matrix. Electron transport appears to be mediated through the PMAS conjugated structure, contrasting with the electron hopping process typically observed in non-conducting metallopolymers. This increased regeneration rate causes the ruthenium-based electrochemiluminescence (ECL) efficiency to be increased. The impact of these observations on the ECL detection of low concentrations of disease biomarkers is discussed.

“…Sulphonic substituents have been introduced by sulphonation of polyaniline with fuming sulphuric acid, leading to partial substitution in the o-position [7±9]. The other route is by polymerising sulphonate-substituted anilines [10,11]. Although successful chemical polymerisation has been reported, e.g.…”

The electrochemical polymerisation of 2-and 4-aminobenzenesulphonic acids (orthanilic acid and sulphanilic acid) in sulphuric acid solution and co-polymerisation of mixtures of aniline and acid monomers, have been systematically investigated. The polymers formed have been characterised voltammetrically. Further evidence concerning the polymer structure and chemical composition has been obtained by IR spectroscopy and scanning electron microscopy (SEM). #

“…Materials thus obtained, however, do not have the same level of conductivity as of the pure ES. The insertion of substituent for example, either in aromatic ring [5][6][7][8] or in the nitrogen atom [9][10][11][12] can improve solubility, but adversely affects the conductivity due to the chain twisting caused by steric effects that decreases the effective conjugation length. The combination of PANI segments with block of another polymer has also been attempted, like the grafting of PANI glycol 13 or poly acrylic acid 14 on to PANI.…”

The present work describes the synthesis of conductive composite of polyurethane sulphonate anionomer (PUSA) and para toluene sulphonic acid doped polyaniline (PANI-PTSA). HCl-doped PANI was synthesized by chemical oxidative polymerization of aniline in HCl, which was converted to PANI-EB by treatment with NH 4 OH. PTSA doped PANI was synthesized from EB-PANI by redoping with PTSA solution. PUSA was synthesized from 4, 4 0 -diphenylmethanediisocyanate (MDI), polypropylene glycol (PPG), 1,4-butanediol (BD), and ionic diol SDOL. The composite was prepared by mixing of the solutions of two polymer components in DMF and then solution casting. The products were characterized and analyzed by UV-Vis and FTIR spectroscopy, thermogravimetry, differential scanning calorimetry and scanning electron microscopy. The conductivity was found to increase by 100 times with concomitant decrease in percolation threshold when polyurethane was replaced by PUSA in the composite for the same amount of polyaniline. The composite film was thermally stable upto 300
