Structural and optical properties of new cyclometalated Ru(II) derived compounds
The electronic spectra of 4 cyclometalated ruthenium compounds built up from cycloruthenated 2-phenylpyridine with monodentate and bidentate ligands, namely 1 [Ru(MeCN)2(phen)(PhPy)]1+ (RDC11), 2 [Ru(phen)2(PhPy)]1+ (RDC34), 3 [Ru(MeCN) 2(PhPy)(dppz)]1+ (RDC11Z), 4 [Ru(bpy)(PhPy)(dppz)] 1+ (RDCbpZ), the last two being newly synthesized, have been recorded and calculated together with that of 5 [Ru(bpy)2(dppz)]2+ (RDNbpZ). Recently synthesized variants of RDC34 where the phenylpyridine ligand is substituted with an electro-attractor or an electro-donor group, 6 [Ru(phen)2(NO2PhPy)]1+ RDC40 and 7 [Ru(phen)2(NH2PhPy)]1+ RDC41 respectively, and the dicationic reference complex [Ru (phen)2(bpy)]2+ (RDN34) have been investigated as well for comparison. The global structures of RDC34 and RDN34 are very similar despite of the substitution of one N atom by one C atom. As expected a shortening of the Ru-C bond as compared to the Ru-N bond is observed. The calculated structures of the investigated complexes point to a rather rigid structure whatever their environment. The introduction of a strong Ru-C bond has a minor effect on the coordination sphere around the metal atom keeping the other Ru-N bonds and bond angles similar, the only noticeable alteration being an increase of the Ru-N bond trans to the Ru-C bond. The experimental spectra are characterized by an intense band in the UV domain centered at 270 nm and corresponding to a strong intra-ligand (IL) absorption. Low-lying MLCT states contribute to a weak shoulder around 370 nm and to a large band between 550 nm and 400 nm. The tail of this band, towards 650 nm, is a characteristic of the cyclometalated complexes. This series of molecules, as other polypyridyl complexes, are characterized by a high density of excited states in the vis/UV energy domain, a large mixing between MLCT/IL and LLCT states in the upper part of the spectrum, and a significant sensitivity to the environment of the IL state localized on the dppz ligands.
