Intersystem crossing to both ligand-localized and charge- transfer excited states in mononuclear and dinuclear ruthenium(II) diimine complexes
The unsaturated bridging ligand 1,4-bis[2-(4'-methyl-2,2' -bipyrid-4-yl)ethenyl]benzene (dstyb) was prepared in a simple two-step sequence. The ruthenium complexes {[(dmb)2Ru](n)(dstyb)}(2n+) (n = 1,2; dmb = 4,4-dimethyl- 2,2'-bipyridine) were
Novel polytopic macrocyclic receptor molecules containing multiple bipyridyl and dibenzo-18-crown-6 units
New polytopic macrocycles (7)-(11) containing multiple 4,4′-disubstituted-2,2′-bipyridyl and dibenzo-18-crown-6 units are described. Preliminary coordination studies reveal these novel ligands form polymetallic complexes with ruthenium and potassium guest cations.
