And now, the host\u2013guest\u2010doped systems have become an effective approach for facilitating RTP, regardless of the still unclear inherent mechanism. In this work, a series of host\u2013guest\u2010doped RTP materials were constructed, and based on experimental results, the \u201cstrong assisting weak\u201d effect was proposed. That is, the host with strong spin\u2010orbit coupling (SOC) effect can effectively enhance the phosphorescence of the guest with weak intersystem crossing (ISC), while maintaining the guest's relatively long lifetime. With 4\u2010dimethylaminopyridine (DMAP) as the host and naphthalene (NL) as the guest, the long RTP lifetime of 1.79\u00a0s could be achieved, which is obviously longer than 0.5\u00a0s of NL@ polymethyl methacrylate (PMMA). Triplet\u2013triplet energy transfer (TTET) process from the dark triplet excitons of DMAP to NL was found to play the key role in triggering RTP of NL. These findings deepen our understandings of RTP mechanisms and provide practical guidance for the creation of highly efficient and long\u2010lived RTP materials.<\/jats:p>","DOI":"10.1002\/anie.202508587","type":"journal-article","created":{"date-parts":[[2025,7,30]],"date-time":"2025-07-30T09:26:43Z","timestamp":1753867603000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["\u201cStrong Assisting Weak\u201d Effect for Long\u2010Lived Room Temperature Phosphorescence in Host\u2013Guest\u2010Doped Systems"],"prefix":"10.1002","volume":"64","author":[{"given":"Kexin","family":"Li","sequence":"first","affiliation":[{"name":"School of Life Sciences Tianjin university  Tianjin 300072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingyue","family":"Qi","sequence":"additional","affiliation":[{"name":"School of Life Sciences Tianjin university  Tianjin 300072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fangting","family":"Li","sequence":"additional","affiliation":[{"name":"School of Life Sciences Tianjin university  Tianjin 300072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yujun","family":"Xie","sequence":"additional","affiliation":[{"name":"Institute of Molecular Aggregation Science Tianjin University  Tianjin 300072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liyao","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Life Sciences Tianjin university  Tianjin 300072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1512-1345","authenticated-orcid":false,"given":"Zhen","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Molecular Aggregation Science Tianjin University  Tianjin 300072 China"},{"name":"Hubei Key Lab on Organic and Polymeric Optoelectronic Materials Department of Chemistry Wuhan University  Wuhan 430072 China"},{"name":"The State Key Laboratory of Luminescent Materials and Devices South China University of Technology  Guangzhou 510640 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,30]]},"reference":[{"key":"e_1_2_7_1_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-024-45844-5"},{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cclet.2024.110629"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-024-47648-z"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11426-020-9761-x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.31635\/ccschem.024.202404116"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsmaterialslett.5c00306"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsanm.4c05457"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.aas9732"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.202317631"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cej.2025.163205"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.4c14920"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.snb.2021.130976"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.202317431"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-021-27914-0"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.202313890"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-025-59367-0"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsami.4c13336"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.202405418"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.202411588"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-018-05298-y"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.202108025"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201901546"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsmaterialslett.4c00104"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.5c02567"},{"key":"e_1_2_7_25_1","doi-asserted-by":"publisher","DOI":"10.1039\/D4SC07768G"},{"key":"e_1_2_7_26_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.analchem.4c00412"},{"key":"e_1_2_7_27_1","doi-asserted-by":"publisher","DOI":"10.1039\/D1SC01175H"},{"key":"e_1_2_7_28_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.202103192"},{"key":"e_1_2_7_29_1","doi-asserted-by":"publisher","DOI":"10.1002\/adom.202303069"},{"key":"e_1_2_7_30_1","first-page":"816","volume":"66","author":"Tu L.","year":"2023","journal-title":"Sci.
