{"page":"468-474","status":"public","abstract":[{"text":"<jats:title>Abstract</jats:title><jats:p>Although iron is a dream candidate to substitute noble metals in photoactive complexes, realization of emissive and photoactive iron compounds is demanding due to the fast deactivation of their charge-transfer states. Emissive iron compounds are scarce and dual emission has not been observed before. Here we report the Fe<jats:sup>III</jats:sup> complex [Fe(ImP)<jats:sub>2</jats:sub>][PF<jats:sub>6</jats:sub>] (HImP = 1,1′-(1,3-phenylene)bis(3-methyl-1-imidazol-2-ylidene)), showing a Janus-type dual emission from ligand-to-metal charge transfer (LMCT)- and metal-to-ligand charge transfer (MLCT)-dominated states. This behaviour is achieved by a ligand design that combines four <jats:italic>N</jats:italic>-heterocyclic carbenes with two cyclometalating aryl units. The low-lying <jats:italic>π</jats:italic>* levels of the cyclometalating units lead to energetically accessible MLCT states that cannot evolve into LMCT states. With a lifetime of 4.6 ns, the strongly reducing and oxidizing MLCT-dominated state can initiate electron transfer reactions, which could constitute a basis for future applications of iron in photoredox catalysis.</jats:p>","lang":"eng"}],"_id":"46481","issue":"4","publication_status":"published","publication_identifier":{"issn":["1755-4330","1755-4349"]},"user_id":"48467","title":"Janus-type emission from a cyclometalated iron(iii) complex","keyword":["General Chemical Engineering","General Chemistry"],"year":"2023","type":"journal_article","intvolume":"        15","author":[{"full_name":"Steube, Jakob","orcid":"0000-0003-3178-4429","id":"40342","first_name":"Jakob","last_name":"Steube"},{"full_name":"Kruse, Ayla","last_name":"Kruse","first_name":"Ayla"},{"last_name":"Bokareva","first_name":"Olga S.","full_name":"Bokareva, Olga S."},{"last_name":"Reuter","first_name":"Thomas","full_name":"Reuter, Thomas"},{"first_name":"Serhiy","last_name":"Demeshko","full_name":"Demeshko, Serhiy"},{"full_name":"Schoch, Roland","orcid":"0000-0003-2061-7289","last_name":"Schoch","id":"48467","first_name":"Roland"},{"first_name":"Miguel A.","last_name":"Argüello Cordero","full_name":"Argüello Cordero, Miguel A."},{"full_name":"Krishna, Athul","last_name":"Krishna","first_name":"Athul"},{"full_name":"Hohloch, Stephan","last_name":"Hohloch","first_name":"Stephan"},{"first_name":"Franc","last_name":"Meyer","full_name":"Meyer, Franc"},{"full_name":"Heinze, Katja","last_name":"Heinze","first_name":"Katja"},{"first_name":"Oliver","last_name":"Kühn","full_name":"Kühn, Oliver"},{"last_name":"Lochbrunner","first_name":"Stefan","full_name":"Lochbrunner, Stefan"},{"id":"47241","first_name":"Matthias","last_name":"Bauer","orcid":"0000-0002-9294-6076","full_name":"Bauer, Matthias"}],"date_updated":"2024-09-05T11:44:07Z","language":[{"iso":"eng"}],"citation":{"chicago":"Steube, Jakob, Ayla Kruse, Olga S.
