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"}],"doi":"10.1021/acs.inorgchem.5c00526","keyword":["Photo"],"publication_status":"published","user_id":"48467","citation":{"short":"L.

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."}],"_id":"58180","date_updated":"2025-08-15T12:30:18Z","date_created":"2025-01-15T08:29:21Z","publication":"Inorganic Chemistry","publisher":"American Chemical Society (ACS)","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0020-1669","1520-510X"]},"year":"2025","type":"journal_article","status":"public"},{"language":[{"iso":"eng"}],"year":"2024","type":"journal_article","publication_identifier":{"issn":["0020-1669","1520-510X"]},"status":"public","date_created":"2024-09-05T11:34:20Z","publication":"Inorganic Chemistry","publisher":"American Chemical Society (ACS)","date_updated":"2025-08-15T12:17:35Z","_id":"56075","doi":"10.1021/acs.inorgchem.4c02576","abstract":[{"text":"An isostructural series of FeII, FeIII, and Fe(IV)complexes [Fe(ImP)2]0/+/2+ utilizing the ImP 1,1′-(1,3-phenylene)-bis(3-methyl-1-imidazol-2-ylidene) ligand, combining N-heterocy-clic carbenes and cyclometalating functions, is presented. 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"}],"title":"Isostructural Series of a Cyclometalated Iron Complex in Three Oxidation States","author":[{"orcid":"0000-0003-3178-4429","full_name":"Steube, Jakob","first_name":"Jakob","id":"40342","last_name":"Steube"},{"last_name":"Fritsch","id":"44418","first_name":"Lorena","full_name":"Fritsch, Lorena"},{"first_name":"Ayla","full_name":"Kruse, Ayla","last_name":"Kruse"},{"first_name":"Olga S.","full_name":"Bokareva, Olga S.","last_name":"Bokareva"},{"last_name":"Demeshko","first_name":"Serhiy","full_name":"Demeshko, Serhiy"},{"orcid":"0000-0002-4945-1481","id":"60250","last_name":"Elgabarty","first_name":"Hossam","full_name":"Elgabarty, Hossam"},{"full_name":"Schoch, Roland","first_name":"Roland","last_name":"Schoch","id":"48467","orcid":"0000-0003-2061-7289"},{"last_name":"Alaraby","full_name":"Alaraby, Mohammad","first_name":"Mohammad"},{"last_name":"Egold","id":"101","first_name":"Hans","full_name":"Egold, Hans"},{"last_name":"Bracht","id":"86707","full_name":"Bracht, Bastian Johannes","first_name":"Bastian Johannes"},{"last_name":"Schmitz","id":"53140","first_name":"Lennart","full_name":"Schmitz, Lennart"},{"full_name":"Hohloch, Stephan","first_name":"Stephan","last_name":"Hohloch"},{"last_name":"Kühne","first_name":"Thomas D.","full_name":"Kühne, Thomas D."},{"last_name":"Meyer","full_name":"Meyer, Franc","first_name":"Franc"},{"last_name":"Kühn","full_name":"Kühn, Oliver","first_name":"Oliver"},{"last_name":"Lochbrunner","first_name":"Stefan","full_name":"Lochbrunner, Stefan"},{"orcid":"0000-0002-9294-6076","first_name":"Matthias","full_name":"Bauer, Matthias","id":"47241","last_name":"Bauer"}],"department":[{"_id":"306"}],"citation":{"short":"J.

Introduction of electron donating and withdrawing groups at the NHC unit modifies the electronic and optical properties, such as the oxidation potential, absorption and emission properties, and the lifetimes of the excited states.</jats:p>"}],"title":"Chemical and photophysical properties of amine functionalized bis‐NHC‐pyridine‐Ru(II) complexes","author":[{"last_name":"Fritsch","id":"44418","first_name":"Lorena","full_name":"Fritsch, Lorena"},{"last_name":"Vukadinovic","first_name":"Yannik","full_name":"Vukadinovic, Yannik"},{"last_name":"Lang","full_name":"Lang, Moritz","first_name":"Moritz"},{"first_name":"Robert","full_name":"Naumann, Robert","last_name":"Naumann"},{"last_name":"Bertrams","first_name":"Maria-Sophie","full_name":"Bertrams, Maria-Sophie"},{"last_name":"Kruse","full_name":"Kruse, Ayla","first_name":"Ayla"},{"id":"48467","last_name":"Schoch","full_name":"Schoch, Roland","first_name":"Roland","orcid":"0000-0003-2061-7289"},{"orcid":"0000-0003-1103-4073","last_name":"Müller","id":"54037","full_name":"Müller, Patrick","first_name":"Patrick"},{"full_name":"Neuba, Adam","first_name":"Adam","last_name":"Neuba"},{"last_name":"Dierks","full_name":"Dierks, Philipp","first_name":"Philipp"},{"last_name":"Lochbrunner","full_name":"Lochbrunner, Stefan","first_name":"Stefan"},{"last_name":"Kerzig","first_name":"Christoph","full_name":"Kerzig, Christoph"},{"last_name":"Heinze","full_name":"Heinze, Katja","first_name":"Katja"},{"last_name":"Bauer","id":"47241","first_name":"Matthias","full_name":"Bauer, Matthias","orcid":"0000-0002-9294-6076"}],"department":[{"_id":"306"}],"citation":{"mla":"Fritsch, Lorena, et al. “Chemical and Photophysical Properties of Amine Functionalized Bis‐NHC‐pyridine‐Ru(II) Complexes.” <i>ChemPhotoChem</i>, Wiley, 2023, doi:<a href=\"https://doi.org/10.1002/cptc.202300281\">10.1002/cptc.202300281</a>.","bibtex":"@article{Fritsch_Vukadinovic_Lang_Naumann_Bertrams_Kruse_Schoch_Müller_Neuba_Dierks_et al._2023, title={Chemical and photophysical properties of amine functionalized bis‐NHC‐pyridine‐Ru(II) complexes}, DOI={<a href=\"https://doi.org/10.1002/cptc.202300281\">10.1002/cptc.202300281</a>}, journal={ChemPhotoChem}, publisher={Wiley}, author={Fritsch, Lorena and Vukadinovic, Yannik and Lang, Moritz and Naumann, Robert and Bertrams, Maria-Sophie and Kruse, Ayla and Schoch, Roland and Müller, Patrick and Neuba, Adam and Dierks, Philipp and et al.}, year={2023} }","ama":"Fritsch L, Vukadinovic Y, Lang M, et al.

Recent success of a cyclometalated iron(III) complex utilizing a bis-tridentate ligand motif inspired the use of phenyl-1H-pyrazole as a bidentate ligand. Five complexes using the tris(1-phenylpyrazolato-N,C2)iron(III) complex scaffold are presented. In addition to the parent complex, four derivatives with functionalization in the meta-position of the phenyl ring are thoroughly investigated by single crystal diffractometry, UV-Vis-spectroscopy, and cyclic voltammetry. Advanced X-ray spectroscopy in the form of X-ray absorption and emission spectroscopy allows unique insights into the electronic structure as well as DFT calculations. The ligand design leads to overlapping MLCT and LMCT absorption bands, and emissive behavior is suppressed by low-lying MC states.</jats:p>"}],"doi":"10.3390/inorganics11070282","title":"Iron(III)-Complexes with N-Phenylpyrazole-Based Ligands","user_id":"48467","keyword":["Photo"],"type":"journal_article","publication":"Inorganics","issue":"7","article_number":"282","volume":11,"intvolume":"        11","author":[{"last_name":"Hirschhausen","full_name":"Hirschhausen, Tanja","first_name":"Tanja"},{"last_name":"Fritsch","id":"44418","first_name":"Lorena","full_name":"Fritsch, Lorena"},{"last_name":"Lux","first_name":"Franziska","full_name":"Lux, Franziska"},{"orcid":"0000-0003-3178-4429","first_name":"Jakob","full_name":"Steube, Jakob","last_name":"Steube","id":"40342"},{"last_name":"Schoch","id":"48467","full_name":"Schoch, Roland","first_name":"Roland","orcid":"0000-0003-2061-7289"},{"last_name":"Neuba","full_name":"Neuba, Adam","first_name":"Adam"},{"full_name":"Egold, Hans","first_name":"Hans","id":"101","last_name":"Egold"},{"last_name":"Bauer","id":"47241","full_name":"Bauer, Matthias","first_name":"Matthias","orcid":"0000-0002-9294-6076"}],"publication_status":"published","citation":{"mla":"Hirschhausen, Tanja, et al. “Iron(III)-Complexes with N-Phenylpyrazole-Based Ligands.” <i>Inorganics</i>, vol. 11, no. 7, 282, MDPI AG, 2023, doi:<a href=\"https://doi.org/10.3390/inorganics11070282\">10.3390/inorganics11070282</a>.","bibtex":"@article{Hirschhausen_Fritsch_Lux_Steube_Schoch_Neuba_Egold_Bauer_2023, title={Iron(III)-Complexes with N-Phenylpyrazole-Based Ligands}, volume={11}, DOI={<a href=\"https://doi.org/10.3390/inorganics11070282\">10.3390/inorganics11070282</a>}, number={7282}, journal={Inorganics}, publisher={MDPI AG}, author={Hirschhausen, Tanja and Fritsch, Lorena and Lux, Franziska and Steube, Jakob and Schoch, Roland and Neuba, Adam and Egold, Hans and Bauer, Matthias}, year={2023} }","short":"T.
