In this work, we reported an organic luminogen with time-dependent afterglow, namely, benzoyleneurea (BEU), with multiple persistent room-temperature phosphorescence (p-RTP) and thermally activated delayed fluorescence (TADF) in single crystals. While the lifetime of TADF is relatively short (~1.2\u2009ms), those for p-RTP are as long as around 369~754\u2009ms. The comparable but different decay rates of diversified p-RTP emissions endow BEU crystals with obvious time-dependent afterglow. The existence of multiple emissions can be reasonably illustrated by the clustering-triggered emission (CTE) mechanism. Single-crystal structure illustrates that the combination of benzene ring and nonconventional chromophores of ureide helps facilitate divergent intermolecular interactions, which contribute to the formation of varying emissive species. Moreover, its methyl- and chloro-substituted derivatives show similar multiple p-RTP emissions. However, no time-dependent afterglows are observed in their crystals, due to the highly approaching lifetimes. The afterglow color variation of BEU crystals grants its applications in advanced anticounterfeiting field and information encryption.<\/jats:p>","DOI":"10.34133\/2021\/9757460","type":"journal-article","created":{"date-parts":[[2021,8,27]],"date-time":"2021-08-27T23:45:07Z","timestamp":1630107907000},"source":"Crossref","is-referenced-by-count":15,"title":["Time-Dependent Afterglow from a Single Component Organic Luminogen"],"prefix":"10.34133","volume":"2021","author":[{"given":"Tianjia","family":"Yang","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Frontiers Science Center for Transformative Molecules, Shanghai Key Lab of Electrical Insulation and Thermal Aging, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8414-659X","authenticated-orcid":false,"given":"Yunzhong","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Frontiers Science Center for Transformative Molecules, Shanghai Key Lab of Electrical Insulation and Thermal Aging, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jixuan","family":"Duan","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Frontiers Science Center for Transformative Molecules, Shanghai Key Lab of Electrical Insulation and Thermal Aging, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuangyu","family":"Wei","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Frontiers Science Center for Transformative Molecules, Shanghai Key Lab of Electrical Insulation and Thermal Aging, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saixing","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Frontiers Science Center for Transformative Molecules, Shanghai Key Lab of Electrical Insulation and Thermal Aging, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6340-3497","authenticated-orcid":false,"given":"Wang Zhang","family":"Yuan","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Frontiers Science Center for Transformative Molecules, Shanghai Key Lab of Electrical Insulation and Thermal Aging, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"221","published-online":{"date-parts":[[2021,8,27]]},"reference":[{"issue":"50","key":"e_1_3_5_1_2","doi-asserted-by":"crossref","first-page":"15589","DOI":"10.1002\/anie.201607653","article-title":"Induction of strong long-lived room-temperature phosphorescence of N-phenyl-2-naphthylamine molecules by confinement in a crystalline dibromobiphenyl matrix","volume":"55","author":"Wei J.","year":"2016","unstructured":"J.
