Although a large library of purely fluorescent compounds exists, emission involving triplet excited states is a rare phenomenon for zinc complexes. We have investigated the photophysical and \u2010chemical properties of a series of dimeric and monomeric Zn<jats:sup>II<\/jats:sup> halide complexes bearing a cyclic (alkyl)(amino)carbene (cAAC) as chromophore unit. Specifically, [(cAAC)XZn(\u03bc\u2010X)<jats:sub>2<\/jats:sub>ZnX(cAAC)] (X=Cl (<jats:bold>1<\/jats:bold>), Br (<jats:bold>2<\/jats:bold>), I (<jats:bold>3<\/jats:bold>)) and [ZnX<jats:sub>2<\/jats:sub>(cAAC)(NCMe)] (X=Br (<jats:bold>4<\/jats:bold>), I (<jats:bold>5<\/jats:bold>)) were isolated and fully characterized, showing intense visible light photoluminescence under UV irradiation at 297\u2005K and fast photo\u2010induced transformation. At 77\u2005K, the compounds exhibit improved stability allowing to record ultra\u2010long lifetimes in the millisecond regime. DFT\/MRCI calculations confirm that the emission stems from <jats:sup>3<\/jats:sup>XCT\/LE<jats:sub>cAAC<\/jats:sub> states and indicate the phototransformation to be related to asymmetric distortion of the complexes by cAAC ligand rotation. This study enhances our understanding of the excited state properties for future development and application of new classes of Zn<jats:sup>II<\/jats:sup> phosphorescent complexes.<\/jats:p>","DOI":"10.1002\/chem.202201114","type":"journal-article","created":{"date-parts":[[2022,5,18]],"date-time":"2022-05-18T09:13:47Z","timestamp":1652865227000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Ultra\u2010Long Lived Luminescent Triplet Excited States in Cyclic (Alkyl)(amino)carbene Complexes of Zn(II) Halides"],"prefix":"10.1002","volume":"28","author":[{"given":"Ond\u0159ej","family":"Mr\u00f3zek","sequence":"first","affiliation":[{"name":"Faculty of Chemistry and Chemical Biology TU Dortmund University  Otto-Hahn-Str. 6 44227 Dortmund Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Gernert","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Chemical Biology TU Dortmund University  Otto-Hahn-Str. 6 44227 Dortmund Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrey","family":"Belyaev","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Chemical Biology TU Dortmund University  Otto-Hahn-Str. 6 44227 Dortmund Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mousree","family":"Mitra","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Chemical Biology TU Dortmund University  Otto-Hahn-Str. 6 44227 Dortmund Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars","family":"Janiak","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Chemical Biology TU Dortmund University  Otto-Hahn-Str. 6 44227 Dortmund Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7148-0900","authenticated-orcid":false,"given":"Christel M.","family":"Marian","sequence":"additional","affiliation":[{"name":"Institute of Theoretical and Computational Chemistry Heinrich Heine University D\u00fcsseldorf  40225 D\u00fcsseldorf Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6952-7391","authenticated-orcid":false,"given":"Andreas","family":"Steffen","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Chemical Biology TU Dortmund University  Otto-Hahn-Str. 6 44227 Dortmund Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,6,21]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr300503r"},{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2020.213371"},{"key":"e_1_2_8_3_1","doi-asserted-by":"crossref","unstructured":"A.
