✦ Synopsis

A series of substituted pyrazino[2,3-f][1,10]-phenanthroline (Rppl) ligands (with R Me, COOH, COOMe) were synthetized (see 1 ± 4 in Scheme 1). The ligands can be visualized as formed by a bipyridine and a quinoxaline fragment (see A and B). Homoleptic [Ru(R 1 ppl) 3 ](PF 6 ) 2 and heteropleptic [Ru(R 1 ppl){(R 2 ) 2 bpy} 2 ](PF 6 ) 2 (R 1 H, Me, COOMe and R 2 H, Me) metal complexes 5 ± 7 and 8 ± 13, respectively, based on these ligands were also synthesized and characterized by conventional techniques (Schemes 2 and 3, resp.). In the heteroleptic complexes, the R 1 -ppl ligand reduces at a less-negative potential than the bpy ligand, reflecting the acceptor property conferred by the quinoxaline moiety. The potentiality of some of these complexes as solar-cell dyes is discussed.
