Tunable Optical and Electrical Properties of Poly(meta-aminophenol) via Doping with FeCl3 and I2 for Advanced Applications
Conjugated conductive organic polymers, such as polyacetylene, polythiophene, polypyrrole, and polyaniline, are among the most widely studied materials due to their unique properties and diverse applications. To explore their potential for advanced technologies, poly(meta-aminophenol) was synthesized and characterized using FTIR, XRD, UV–Vis spectroscopy, TGA, and electrical measurements. The optical properties of the doped polymer were investigated through oxidation-reduction reactions using FeCl3 and I2 to analyze its redox behavior. Upon doping, the energy gap of the polymers decreased, influenced by the oxidation potential of the dopants. The undoped polymer exhibited an energy gap of 3.4 eV, which reduced to 1.8 eV for the I2-doped polymer and 2.05 eV for the FeCl3-doped polymer. This reduction in energy gap correlated with an increase in electrical conductivity, from 8.85 × 10−4 S/m for the undoped polymer to 7.28 × 10–3 S/m for the I2-doped polymer and 4.22 × 10−3 S/m for the FeCl3-doped polymer.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
