Transient decay analysis confirms its phosphorescent nature, revealing a remarkably long lifetime of 2.92\u2005ms. Periodic density functional theory (DFT) calculations reveal a direct band gap of 1.94\u2005eV and, critically, a spatially separated electronic structure where the highest occupied crystalline orbital is localized exclusively on the inorganic [MnCl\n                    <jats:sub>4<\/jats:sub>\n                    ]\n                    <jats:sup>2\u2212<\/jats:sup>\n                    anion and the lowest unoccupied orbital resides solely on the organic [CTP]\n                    <jats:sup>+<\/jats:sup>\n                    cation. This clear spatial separation defines the primary photoexcitation as an inter-ionic charge transfer from the anion to the cation, which effectively suppresses nonradiative recombination pathways and is identified as the key factor enabling the observed long-lived phosphorescence. This study not only reports a new efficient green phosphor based on an earth-abundant metal, but also demonstrates that engineering a spatially segregated charge-transfer state is a viable strategy for achieving persistent luminescence in hybrid materials.\n                  <\/jats:p>","DOI":"10.1107\/s2053229626005310","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T08:44:08Z","timestamp":1779353048000},"page":"294-300","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["An Mn\n                    <sup>2+<\/sup>\n                    -based organic\u2013inorganic hybrid with spatially separated charge transfer for efficient green phosphorescence"],"prefix":"10.1107","volume":"82","author":[{"given":"Wenhui","family":"Wu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiong","family":"Fu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haojie","family":"Ren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyue","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiakai","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingying","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingyuan","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziyang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiani","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,5,26]]},"reference":[{"key":"oj3042_bb1","unstructured":"Bruker (2016).
