(3,5\u2010Dichloro\u20104\u2010pyridyl)bis(2,4,6\u2010trichlorophenyl)methyl radical (PyBTM) was photoluminescent under various conditions. Fluorescence quantum yields of 0.03, 0.26, and 0.81 (the highest value reported for a stable organic radical) were obtained in chloroform, in poly(methyl methacrylate) film at room temperature, and in an EPA matrix (diethyl ether:isopentane:ethanol) at 77\u2005K, respectively. The photostability of PyBTM is up to 115\u2005times higher than that of the tris(2,4,6\u2010trichlorophenyl)methyl radical, a previously reported luminescent radical. The pyridine moiety of PyBTM acts as a proton coordination site, thereby allowing for control of the electronic and optical properties of the radical by protonation and deprotonation.<\/jats:p>","DOI":"10.1002\/anie.201407362","type":"journal-article","created":{"date-parts":[[2014,9,11]],"date-time":"2014-09-11T16:36:17Z","timestamp":1410453377000},"page":"11845-11848","source":"Crossref","is-referenced-by-count":248,"title":["Luminescence, Stability, and Proton Response of an Open\u2010Shell (3,5\u2010Dichloro\u20104\u2010pyridyl)bis(2,4,6\u2010trichlorophenyl)methyl Radical"],"prefix":"10.1002","volume":"53","author":[{"given":"Yohei","family":"Hattori","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuro","family":"Kusamoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Nishihara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2014,9,11]]},"reference":[{"key":"e_1_2_2_1_2","unstructured":"\u00a0"},{"key":"e_1_2_2_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature04645"},{"key":"e_1_2_2_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature11687"},{"key":"e_1_2_2_4_2","unstructured":"\u00a0"},{"key":"e_1_2_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tet.2005.05.043"},{"key":"e_1_2_2_6_2","doi-asserted-by":"publisher","DOI":"10.1039\/b925092a"},{"key":"e_1_2_2_7_2","unstructured":"\u00a0"},{"key":"e_1_2_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetlet.2006.02.022"},{"key":"e_1_2_2_9_2","doi-asserted-by":"publisher","DOI":"10.1021\/jo0708846"},{"key":"e_1_2_2_10_2","doi-asserted-by":"publisher","DOI":"10.1021\/jo4028215"},{"key":"e_1_2_2_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/jp908425w"},{"key":"e_1_2_2_12_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja070946"},{"key":"e_1_2_2_13_2","unstructured":"\u00a0"},{"key":"e_1_2_2_14_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja00257a030"},{"key":"e_1_2_2_15_2","doi-asserted-by":"publisher","DOI":"10.1021\/j100103a025"},{"key":"e_1_2_2_16_2","doi-asserted-by":"publisher","DOI":"10.1021\/j100306a023"},{"key":"e_1_2_2_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tet.2006.04.022"},{"key":"e_1_2_2_18_2","doi-asserted-by":"publisher","DOI":"10.1021\/jo00241a026"},{"key":"e_1_2_2_19_2","unstructured":"CCDC\u20101006484 (PyBTM) and 1006485 ([NH\u2010PyBTMH]\u22c5BF4\u22c5H2O) contain the supplementary crystallographic data for this paper.
