However, terpolymer donors typically exhibit negative effects on molecular stacking and weaken charge transport due to the irregular distribution of the polymer skeleton. Herein, two terpolymers PBBQ\u20105 (5% ff\u2010Qx) and PBBQ\u201010 (10% ff\u2010Qx) are developed by introducing the difluoro\u20102\u2010(3\u2010hexyldecyloxy) quinoxaline (ff\u2010Qx) to the main chain of PM6. The introduction of ff\u2010Qx unit not only enables the terpolymers to possess N\u00b7\u00b7\u00b7S noncovalent intramolecular interactions that contribute to enlarge molecular planarity and enhance intramolecular interaction but also can fine\u2010tuning electrostatic potential (ESP) values of the related polymers, thereby regulate intermolecular interactions with acceptor by electrostatic force. After blending with L8\u2010BO, the PBBQ\u20105:L8\u2010BO\u2010based blend film exhibits appreciated miscibility, desirable phase separation sizes, and more ordered molecular packing than the analogs. Consequently, an impressive power conversion efficiency (PCE) as high as 19.54% is realized in PBBQ\u20105\u2010based devices, which set a new record for Qx\u2010based polymer solar cells. The work emphasizes the drawbacks of terpolymers and provides a new pathway for developing high\u2010performance polymer donors by optimizing intra\/inter\u2010molecular interaction.<\/jats:p>","DOI":"10.1002\/smll.202410198","type":"journal-article","created":{"date-parts":[[2025,1,6]],"date-time":"2025-01-06T06:11:21Z","timestamp":1736143881000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Fine\u2010Tuning Intra\/Inter\u2010Molecular Interaction via Ternary Copolymerization Strategy to Obtain Efficient Polymer Donors"],"prefix":"10.1002","volume":"21","author":[{"given":"Liqing","family":"Li","sequence":"first","affiliation":[{"name":"Jiangxi Province Key Laboratory of Functional Crystalline Materials Chemistry School of Chemistry and Chemical Engineering Jiangxi University of Science and Technology  156 Ke Jia Avenue Ganzhou 341000 P.
