Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 60804-74-2, is researched, Molecular C30H24F12N6P2Ru, about Excited-State Dipole Moments of Homoleptic [Ru(bpy’)3]2+ Complexes Measured by Stark Spectroscopy, the main research direction is dipole moment homoleptic ruthenium bipyridine complex Stark spectroscopy.Related Products of 60804-74-2.
The visible absorption and Stark spectra of five [Ru(4,4′-R-2,2′-bipyridine)3](PF6)2 and [Ru(bipyrazine)3(PF6)2 complexes, where R = CH3O-, tert-butyl-, CH3-, H-, or CF3-, were obtained in butyronitrile glasses at 77K as a function of the applied field in the 0.2-0.8 MV/cm range. Anal. of the metal-to-ligand charge-transfer (MLCT) absorption and Stark spectra with the Liptay treatment revealed dramatic light-induced dipole moment changes, Δμ = 5-11 D. Application of a two-state model to the Δμ values provided values of the metal-ligand electronic coupling, HDA = 4400-6600 cm-1, reasonable for this class of complexes. The ground state of these complexes has no net dipole moment and with the RuII center as the point of reference, the dipole moment changes were reasonably assigned to the dipole present in the initially formed MLCT excited state. Further, the excited state dipole moment was sensitive to the presence of electron donating (MeO-, tert-butyl-, CH3-) or withdrawing (CF3-) substituents on the bipyridine ligands, and Δμ was correlated with the substituent Hammett parameters. Hence the data show for the first time that substituents on the bipyridine ligands, that are often introduced to tune formal reduction potentials, can also induce significant changes in the excited state dipole, behavior that should be taken into consideration for artificial photosynthesis applications.
