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.
Synthesis, optical, and thermal properties of conjugated, bispyridyl and tetrapyridyl compounds by Knoevenagel reaction
A series of conjugated, bispyridyl and tetrapyridyl compounds were synthesized from either terephthalaldehyde or isophthalaldehyde and activated pyridyl compounds by Knoevenagel reaction on heating in acetic anhydride in presence of acetic acid and their
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
