摘要: Two series of bidentate polypyridine ligands, made phenanthroline chelating subunits having substituted mono-and di-anthracenyl groups, and 1-methoxy-1-buten-3-yne at the 4 7-positions with corresponding heteroleptic Ru(II) complex have been synthesized characterized. The is formulated as [(Ru(L1)(L2)(NCS)2)], (where L1 = 4-(9-dianthracenyl-10-(2,3-dimethylacrylic acid)-7-(9-anthracenyl-10-(2,3-dimethylacrylic acid)-1,10-phenanthroline L2 4,7-bis(1-methoxy-1-buten-3-yne)-1,10-phenanthroline). shows characteristic broad intense metal-to-ligand charge transfer (MLCT) bands absorption appreciable photoluminescence spanning visible region. ligands were characterized by FT-IR, 1H, 13C NMR spectroscopy, UV-Vis, elemental analysis (see in supplementary materials). anchoring groups both allowed an extended delocalization acceptor orbital charge-transfer excited state.
