Abstract

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.

通过FeCl3和I2掺杂聚间氨基苯酚的可调光学和电学性质在高级应用中的应用

共轭导电有机聚合物，如聚乙炔、聚噻吩、聚吡咯和聚苯胺，由于其独特的性能和多样化的应用，是研究最广泛的材料之一。为了探索其先进技术的潜力，合成了聚（间氨基酚），并使用FTIR， XRD， UV-Vis光谱，TGA和电测量对其进行了表征。通过FeCl3和I2的氧化还原反应研究了掺杂聚合物的光学性质，分析了其氧化还原行为。掺杂后，受掺杂物氧化电位的影响，聚合物的能隙减小。未掺杂聚合物的能隙为3.4 eV， i2掺杂聚合物的能隙为1.8 eV， fecl3掺杂聚合物的能隙为2.05 eV。这种能隙的减小与电导率的增加相关，从未掺杂聚合物的8.85 × 10 - 4 S/m到掺杂i2的7.28 × 10 - 3 S/m和掺杂fecl3的4.22 × 10 - 3 S/m。
