To increase excited state lifetimes of iron complexes, the multichromophoric approach is promising, combining organic chromophores with photoactive iron complexes, potentially enabling a reservoir effect. We present a series of chromophore-functionalized complexes based on the parental FeIII complex [Fe(ImP)2][PF6] (HImP = 1,1′-(1,3-phenylene)bis(3-methyl-1-imidazole-2-ylidene)). The four organic chromophores benzene, naphthalene, anthracene, and pyrene are attached to the ImP-ligand in para-position to the coordination site to systematically investigate the influence of the steric demand and electronic properties of the chromophore on charge transfer lifetimes as well as photodynamics. A thorough ground state characterization was conducted in addition to investigations of the excited state dynamics by transient absorption spectroscopy and streak camera emission measurements. The conclusions drawn are supported by extensive DFT calculations. The emission coefficients could be significantly improved by the addition of chromophores. After excitation of the complexes with larger chromophores, coplanarization of the backbone and complex motif occurs to stabilize the formal charge. This results in population of a superligand state that exhibits a much faster radiationless relaxation to the ground state compared to the parent complex, hindering a reservoir effect.","lang":"eng"}],"status":"public","_id":"60600","user_id":"48467","department":[{"_id":"306"}],"article_number":"acs.inorgchem.5c00526","keyword":["Photo"],"language":[{"iso":"eng"}]},{"status":"public","abstract":[{"text":"A series of CoIII complexes [Co(RImP)2][PF6], with HMeImP = 1,1′-(1,3-phenylene)bis(3-methyl-1-imidazole-2-ylidene)) and R = Me, Et, iPr, nBu, is presented in this work. The influence of the strong donor ligand on the ground and excited-state photophysical properties was investigated in the context of different alkyl substituents at the imidazole nitrogen. X-ray diffraction revealed no significant alterations of the structures and all differences in the series emerge from the electronic structures. These were probed via cyclic voltammetry and UV–vis spectroscopy, detailing the influence of the different alkyl substituents on the ground-state properties. All complexes are emissive at 77 K from a 3MC state, which exhibits lifetimes in the range of 1–5 ns at room temperature, depending on the alkyl substituent. Therefore, it is clearly shown that even small differences in the electronic structure have a large impact on the details of the excited state landscape. The observed behavior was rationalized by a detailed DFT analysis, which shows that the minimum-energy crossing point to the ground-state is located only slightly above the MC energy: Consequently, nonradiative decay to the ground state at room temperature is enabled, while at 77 K this path is prohibited, leading to low-temperature 3MC emission.","lang":"eng"}],"type":"journal_article","publication":"Inorganic Chemistry","language":[{"iso":"eng"}],"keyword":["Photo"],"user_id":"48467","department":[{"_id":"306"}],"_id":"58180","citation":{"mla":"Krishna, Athul, et al. “Low Temperature Emissive Cyclometalated Cobalt(III) Complexes.” <i>Inorganic Chemistry</i>, American Chemical Society (ACS), 2025, doi:<a href=\"https://doi.org/10.1021/acs.inorgchem.4c04479\">10.1021/acs.inorgchem.4c04479</a>.","bibtex":"@article{Krishna_Fritsch_Steube_Argüello Cordero_Schoch_Neuba_Lochbrunner_Bauer_2025, title={Low Temperature Emissive Cyclometalated Cobalt(III) Complexes}, DOI={<a href=\"https://doi.org/10.1021/acs.inorgchem.4c04479\">10.1021/acs.inorgchem.4c04479</a>}, journal={Inorganic Chemistry}, publisher={American Chemical Society (ACS)}, author={Krishna, Athul and Fritsch, Lorena and Steube, Jakob and Argüello Cordero, Miguel A. and Schoch, Roland and Neuba, Adam and Lochbrunner, Stefan and Bauer, Matthias}, year={2025} }","short":"A.

The strong donor motif stabilizes the high-valent Fe(IV) oxidation state yet keeps the FeII oxidation state accessible from the parent Fe(III)compound. Chemical oxidation of [Fe(ImP)2]+ yields stable [FeIV(ImP)2]2+. In contrast, [FeII(ImP)2]0, obtained by reduction,is highly sensitive toward oxygen. Exhaustive ground state characterization by single-crystal X-ray diffraction, 1H NMR,Mössbauer spectroscopy, temperature-dependent magnetic measurements, a combination of X-ray absorption near edge structureand valence-to-core, as well as core-to-core X-ray emission spectroscopy, complemented by detailed density functional theory (DFT) analysis, reveals that the three complexes[Fe(ImP)2]0/+/2+ can be unequivocally attributed to low-spin d6, d5, and d4 complexes. The excited state landscape of the Fe(II) and Fe(IV) complexes is characterized by short-lived 3MLCT and 3LMCT states, with lifetimes of 5.1 and 1.4 ps, respectively. In the FeII-compound, an energetically low-lying MC state leads to fast deactivation of the MLCT state. The distorted square-pyramidal state, where one carbene is dissociated, can not only relax into the ground state, but also into a singlet dissociated state. Its formation was investigated with time-dependent optical spectroscopy, while insights into its structure were gained by NMR spectroscopy.","lang":"eng"}],"status":"public","date_updated":"2025-08-15T12:17:35Z","publisher":"American Chemical Society (ACS)","author":[{"first_name":"Jakob","orcid":"0000-0003-3178-4429","last_name":"Steube","id":"40342","full_name":"Steube, Jakob"},{"first_name":"Lorena","last_name":"Fritsch","full_name":"Fritsch, Lorena","id":"44418"},{"first_name":"Ayla","last_name":"Kruse","full_name":"Kruse, Ayla"},{"first_name":"Olga S.","full_name":"Bokareva, Olga S.","last_name":"Bokareva"},{"full_name":"Demeshko, Serhiy","last_name":"Demeshko","first_name":"Serhiy"},{"last_name":"Elgabarty","orcid":"0000-0002-4945-1481","id":"60250","full_name":"Elgabarty, Hossam","first_name":"Hossam"},{"last_name":"Schoch","orcid":"0000-0003-2061-7289","full_name":"Schoch, Roland","id":"48467","first_name":"Roland"},{"first_name":"Mohammad","last_name":"Alaraby","full_name":"Alaraby, Mohammad"},{"last_name":"Egold","full_name":"Egold, Hans","id":"101","first_name":"Hans"},{"first_name":"Bastian Johannes","last_name":"Bracht","id":"86707","full_name":"Bracht, Bastian Johannes"},{"last_name":"Schmitz","id":"53140","full_name":"Schmitz, Lennart","first_name":"Lennart"},{"first_name":"Stephan","last_name":"Hohloch","full_name":"Hohloch, Stephan"},{"first_name":"Thomas D.","full_name":"Kühne, Thomas D.","last_name":"Kühne"},{"first_name":"Franc","full_name":"Meyer, Franc","last_name":"Meyer"},{"first_name":"Oliver","last_name":"Kühn","full_name":"Kühn, Oliver"},{"first_name":"Stefan","full_name":"Lochbrunner, Stefan","last_name":"Lochbrunner"},{"first_name":"Matthias","id":"47241","full_name":"Bauer, Matthias","last_name":"Bauer","orcid":"0000-0002-9294-6076"}],"date_created":"2024-09-05T11:34:20Z","title":"Isostructural Series of a Cyclometalated Iron Complex in Three Oxidation States","doi":"10.1021/acs.inorgchem.4c02576","publication_identifier":{"issn":["0020-1669","1520-510X"]},"publication_status":"published","year":"2024","citation":{"ama":"Steube J, Fritsch L, Kruse A, et al.

However, the substitution of noble metals, which are almost exclusively used, by base metals remains a major challenge on the way to a more sustainable world.1 Iron is a dream candidate for this ambitious aim.2 But compared to noble metal complexes that show long-lived metal-to-ligand charge-transfer (MLCT) states, realization of emissive and photoactive iron complexes is demanding, due to the fast deactivation of charge transfer states into non-emissive inactive states. No MLCT emission has been observed for monometallic iron complexes before. Consequently, dual emission could also not yet be realized with iron complexes, as it is a very rare property even of noble metal compounds. 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 Janus-type dual emission by combining LMCT (ligand-to-metal charge transfer) with MLCT luminescence. The respective excited states are characterized by a record lifetime of τ<jats:sub>MLCT</jats:sub> = 4.2 ns, and a moderate τ<jats:sub>LMCT</jats:sub> = 0.2 ns. Only two emissive Fe<jats:sup>III</jats:sup> compounds are known so far and they show LMCT luminescence only.3,4 The unique properties of the presented complex are caused by the specific ligand design combining four N-heterocyclic carbenes with two cyclometalating groups, using the σ-donor strength of six carbon atoms and the acceptor capabilities of the central phenyl rings. Spectroscopically, doublet manifolds could be identified in the deactivation process, while (TD)DFT analysis revealed the presence of quartets as well. With three key advancements of realizing the first iron complex showing dual luminescence, a MLCT luminescence and a world record MLCT lifetime, the results constitute a basis for future application of iron complexes as white light emitters and new photocatalytic reactions making use of the Janus-type properties of the developed complex.","lang":"eng"}],"type":"preprint","language":[{"iso":"eng"}],"department":[{"_id":"35"},{"_id":"306"}],"user_id":"48467","_id":"40994"},{"publication":"Chemistry – A European Journal","type":"journal_article","status":"public","department":[{"_id":"43"},{"_id":"35"},{"_id":"306"}],"user_id":"48467","_id":"16312","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0947-6539","1521-3765"]},"publication_status":"published","page":"11826-11830","citation":{"ieee":"J.
