Polymeric semiconductors offer the dual advantages of lightness and flexibility, facilitating the large-scale production of organic electronic devices. In the present research, electron donor polymers were synthesized incorporating high electron density aromatic units, specifically benzodithiophene (BDT) and thiophene (Th), to explore their efficacy in organic electronics. This systematic study focused on evaluating the impact of varying side chains on the material properties of these polymers. It was found that polymers with Th side chains exhibited significantly enhanced thermal stability, approximately 100°C higher than their alkoxide side chain counterparts. For the polymer PEHO-BDT3HT, a bandgap value of around 1.6 eV was obtained. Furthermore, binary devices were developed using these novel copolymers, among which PDT-BDT3HT demonstrated superior photovoltaic performance, achieving a power conversion efficiency of 1.56% without any optimization. This work not only sheds light on the influence of side chain variations in polymer properties but also showcases the potential of BDT and Th-based copolymers in the field of organic electronics.

不同侧链对有机太阳能电池中苯并二噻吩和噻吩交替共聚物的影响

聚合物半导体具有轻便和柔性的双重优势，有利于有机电子器件的大规模生产。在本研究中，合成了包含高电子密度芳香族单元，特别是苯并二噻吩（BDT）和噻吩（Th）的电子给体聚合物，以探索它们在有机电子学中的功效。这项系统研究的重点是评估不同侧链对这些聚合物材料性能的影响。研究发现，具有 Th 侧链的聚合物表现出显着增强的热稳定性，比其醇盐侧链对应物高约 100°C。对于聚合物PEHO-BDT3HT，获得了约1.6 eV的带隙值。此外，利用这些新型共聚物开发了二元器件，其中PDT-BDT3HT表现出优异的光伏性能，在没有任何优化的情况下实现了1.56%的功率转换效率。这项工作不仅揭示了侧链变化对聚合物性能的影响，而且展示了BDT和Th基共聚物在有机电子领域的潜力。
