Abstract：

Conjugated　polymers　(CPs)　are　widely　used　as　conductive　materials　in　various　applications,　with　their　conductive　properties　adjustable　through　chemical　doping.　While　doping　enhances　the　thermoelectric　properties　of　CPs　due　to　improved　main-chain　transport,　overdoping　can　distort　the　polymer　structure,　increasing　energy　disorder　and　impeding　intrinsic　electrical　transport.　This　study　explored　how　different　dopants　affect　the　structural　integrity　and　electrical　transport　properties　of　CPs.　We　found　that　dopants　vary　in　their　impact　on　CP　structure,　consequently　altering　their　electrical　transport　capabilities.　Specifically,　ferric　chloride　(FeCl3)-doped　indacenodithiophene-co-benzothiadiazole　(IDTBT)　shows　superior　electrical　transport　properties　to　triethyloxonium　hexachloroantimonate　(OA)-doped　IDTBT　due　to　enhanced　backbone　planarity　and　rigidity,　which　facilitate　carrier　transport　and　lower　energetic　disorder.　These　results　highlight　the　critical　role　of　dopant　selection　in　optimizing　CPs　for　advanced　applications,　suggesting　that　strategic　dopant　choices　can　significantly　refine　the　charge　transport　characteristics　of　CPs,　paving　the　way　for　their　industrialization.　©　2024　by　the　authors.
