Photoactive metal complexes containing earth-abundant transition metals recently gained interest as photosensitizers in light-driven chem. In contrast to the traditionally employed ruthenium or iridium complexes, iron complexes developed to be promising candidates despite the fact that using iron complexes as photosensitizers poses an inherent challenge associated with the low-lying metal-centered states, which are responsible for ultrafast deactivation of the charge-transfer states. Nonetheless, recent developments of strongly σ-donating carbene ligands yielded highly promising systems, in which destabilized metal-centered states resulted in prolonged lifetimes of charge-transfer excited states. In this context, we introduce a series of novel homoleptic Fe-triazolylidene mesoionic carbene complexes. The excited-state properties of the complexes were investigated by time-resolved femtosecond transient absorption spectroscopy and quantum chem. calculations Pump wavelength-dependent transient absorption reveals the presence of distinct excited-state relaxation pathways. We relate the excitation-wavelength-dependent branching of the excited-state dynamics into various reaction channels to solvent-dependent photodissociation following the population of dissociative metal centered states upon excitation at 400 nm. In addition to this study using 2,6-Dibromopyridine, there are many other studies that have used 2,6-Dibromopyridine(cas: 626-05-1COA of Formula: C5H3Br2N) was used in this study.
2,6-Dibromopyridine(cas: 626-05-1) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. COA of Formula: C5H3Br2N
