Abstract

Two polymer donors, PATz3T-o6BO and PATz3T-o6HD, incorporating alkoxy-substituted anthra[1,2-c:5,6-c']bis([1,2,5]thiadiazole), were strategically designed and synthesized. The unique wavy backbone of these polymers effectively reduced aggregation, leading to enhanced solubility and significantly improved molecular ordering. Consequently, the PATz3T-o6HD:Y12-based solar cells achieved a power conversion efficiency (PCE) of 7.94%. These findings provide valuable insights into the molecular design of high-performance polymer donors for organic photovoltaics (OPVs).

有机光伏用烷氧基取代炭疽（噻二唑）-噻吩共聚物：独特的波浪形骨架增强聚集、分子秩序和器件效率。

以烷氧基取代炭疽[1,2-c:5,6-c']双（[1,2,5]噻二唑）为原料，设计并合成了两种聚合物给体PATz3T-o6BO和PATz3T-o6HD。这些聚合物独特的波浪骨架有效地减少了聚集，从而提高了溶解度，并显着改善了分子的有序性。因此，基于PATz3T-o6HD: y12的太阳能电池实现了7.94%的功率转换效率（PCE）。这些发现为有机光伏（OPVs）高性能聚合物供体的分子设计提供了有价值的见解。

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
