While conventional doping strategies have historically relied on direct redox-reaction chemistry governed by strict frontier molecular orbital alignment, the field has recently transitioned toward a multimechanism paradigm. In this Perspective, we critically evaluate emerging doping mechanisms that bypass traditional thermodynamic and morphological limitations, focusing on ion-exchange, catalytic activation, electrophilic and nucleophilic attacks, and deprotonation-induced pathways. We establish a comprehensive physical chemistry framework comparing these strategies, demonstrating how local chemical transformations and covalent-mediated pathways not only expand the library of dopable organic semiconductors but also offer profound physical-chemical advantages including superior doping efficiency, enhanced host-dopant miscibility, and exceptional environmental stability. Finally, we outline the key challenges and future milestones required to transition these highly efficient doping protocols into practical industrial technologies, highlighting the urgent need for precise spatial patterning, long-term operational and environmental stabilization under real-world stress, and the translation of efficient doping to advanced functional devices.<\/jats:p>","DOI":"10.1021\/acs.jpclett.6c02115","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T06:02:15Z","timestamp":1790661735000},"page":"11305-11319","source":"Crossref","is-referenced-by-count":0,"title":["Emerging Doping\nParadigms in Organic Semiconductors"],"prefix":"10.1021","volume":"17","author":[{"given":"Jing","family":"Guo","sequence":"first","affiliation":[{"name":"Hunan University , , ,","place":["Changsha, China, 410082"]},{"name":"Hunan University , , ,","place":["Changsha, China, 410082"]},{"name":"Shanxi Normal University , , ,","place":["Taiyuan, China, 030031"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huan","family":"Wei","sequence":"additional","affiliation":[{"name":"Hunan University , , ,","place":["Changsha, China, 410082"]},{"name":"Hunan University , , ,","place":["Changsha, China, 410082"]},{"name":"Henan University , , ,","place":["Kaifeng, China, 475004"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenpei","family":"Shi","sequence":"additional","affiliation":[{"name":"Hunan University , , ,","place":["Changsha, China, 410082"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4868-3600","authenticated-orcid":true,"given":"Xue","family":"Zhang","sequence":"additional","affiliation":[{"name":"South China University of Technology , , ,","place":["Guangzhou, China, 511442"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3624-1618","authenticated-orcid":true,"given":"Lang","family":"Jiang","sequence":"additional","affiliation":[{"name":"Hebei University of Technology , , ,","place":["Tianjin, China, 300130"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8511-1401","authenticated-orcid":true,"given":"Yuanyuan","family":"Hu","sequence":"additional","affiliation":[{"name":"Hunan University , , ,","place":["Changsha, China, 410082"]},{"name":"Hunan University , , ,","place":["Changsha, China, 410082"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,29]]},"reference":[{"issue":"25","key":"2026100811165670900_cit1","doi-asserted-by":"publisher","first-page":"2400342","DOI":"10.1002\/adma.202400342","article-title":"Self-Assembled\nInterlayer Enables High-Performance\nOrganic Photovoltaics with Power Conversion Efficiency Exceeding 20%","volume":"36","author":"Guan","year":"2024","journal-title":"Adv.
