Conductive polymers facilitate the electrical current flow through the transfer of electrons and holes. They show promise for novel photo-functional materials in photovoltaics. However, substantial electrostatic interactions between electron donors and acceptors induce polymer aggregation, limiting moldability and conductivity. In this study, robust donor polymers with high heat resistance were synthesized by bonding triphenylamine (TPA) derivatives and formaldehyde to phenolic groups. Resulting TPA-based phenolic polymers exhibited flexible structures and fluorescence due to charge transfer with acceptor molecules. Furthermore, TPA-based phenolic polymers' capacity to distinguish acceptor molecule sizes correlated with their molecular weight, reflecting upon donor-acceptor interactions. This novel optical trait in phenolic polymers holds potential for electronic components and conductive materials.
导电聚合物通过电子和空穴的转移促进电流流动。它们在光伏领域作为新型光功能材料展现出前景。然而，电子供体和受体之间大量的静电相互作用会导致聚合物聚集，限制了可模塑性和导电性。在本研究中，通过将三苯胺（TPA）衍生物与甲醛键合到酚基上，合成了具有高耐热性的坚固供体聚合物。所得的基于TPA的酚醛聚合物由于与受体分子的电荷转移而呈现出灵活的结构和荧光。此外，基于TPA的酚醛聚合物区分受体分子大小的能力与其分子量相关，这反映了供体-受体相互作用。酚醛聚合物的这种新型光学特性在电子元件和导电材料方面具有潜力。
