Here, we report a confined magnetic bipolaron strategy to achieve efficient, thermally stable PL in Mn2+-doped 2D benzimidazolium lead chloride perovskite. Via synergy of directional coordination, interlayer confinement, and hydrogen bonding, we form ferromagnetically coupled Mn\u2013Cl\u2013Mn pairs as confined magnetic bipolaron emission centers, moderating electron\u2013phonon coupling and suppressing nonradiative recombination. The optimized material shows 623 nm orange-red emission with 96.9% room-temperature PLQY, 99.6% color purity, and 84% peak intensity retention at 400 K. This work opens a new route to stabilize photoexcited states for high-performance perovskite emitters.<\/jats:p>","DOI":"10.1021\/acs.jpclett.6c00861","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T13:01:57Z","timestamp":1784725317000},"page":"8935-8943","source":"Crossref","is-referenced-by-count":1,"title":["High-Efficiency\nConfined Magnetic Bipolaron Emission\nin Mn2+-Doped 2D Benzimidazolium Lead Chloride"],"prefix":"10.1021","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-5582-5856","authenticated-orcid":true,"given":"Yuewei","family":"Shi","sequence":"first","affiliation":[{"name":"Guangxi University , , ,","place":["Nanning, China, 530004"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuaigang","family":"Ge","sequence":"additional","affiliation":[{"name":"Guangxi University , , ,","place":["Nanning, China, 530004"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-7231-8914","authenticated-orcid":true,"given":"Xiaodong","family":"Shen","sequence":"additional","affiliation":[{"name":"Guangxi University , , ,","place":["Nanning, China, 530004"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongyu","family":"Wu","sequence":"additional","affiliation":[{"name":"Guangxi University , , ,","place":["Nanning, China, 530004"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4561-4711","authenticated-orcid":true,"given":"Bingsuo","family":"Zou","sequence":"additional","affiliation":[{"name":"Guangxi University , , ,","place":["Nanning, China, 530004"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,22]]},"reference":[{"issue":"39","key":"2026080609092273100_cit1","doi-asserted-by":"publisher","first-page":"2204579","DOI":"10.1002\/adfm.202204579","article-title":"Two-dimensional\nperovskites with tunable room-temperature phosphorescence","volume":"32","author":"Wu","year":"2022","journal-title":"Adv.
