  detailed photophysical investigation of two dinuclear ruthenium(II) complexes is reported. The two metallic centers were coordinated to a bis-2,2′-bipyridine bridging ligand, connected either through the para (Lp, Dp) or the meta position (Lm, Dm). The results obtained herein were compared to the prototypical [Ru(bpy)3]2+ parent compound. The formation of dinuclear complexes was accompanied by the expected

  The synthesis of ruthenium(II) complexes with 2,2′-bipyridine and 1,10-phenanthroline as ligands is described. These ligands were prepared using reactions of our new and simple ‘LEGO’ System. ‘LEGO’ system reactions which are possible with the free, uncoordinated ligands also apply to coordinated ligands.

  A series of TiO2-supported copper(I) dyes, [CL(L-anchor) (L-ancillary)](+) with L-ancillary = 2,2':4',4":2",2"'-quaterpyridine (1), 4,4'-bis(6-methyl-[2,2'-bipyridin]-4-yl)-1,1'-biphenyl (2), or 4,4'-bis(6,6'-dimethyl-[2,2'-bipyridin]-4-y1)-1,1'-biphenyl (3), and Lanchor = (6,6'-dimethyl-[2,2'-bipyridine]-4,4'-diyl)bis(4,1-phenylene)bis(phosphonic acid) (4), has been assembled in a stepwise manner. DSSCs incorporating these dyes demonstrate the need for 6,6'-substituents in both ligands in [CU(L-anchor) (L-ancillary)]+; both J(sc) and V-oc increase on going from [Cu(4) (1)](+) to [Cu(4) (2)](+) to [Cu(4) (3)](+). First second and third generation dyes [(4)Cu(3)}(n)](n+) (n = 1, 2 or 3) have been assembled using the 'surfaces-as-ligands, surfaces-as-complexes' strategy, although the separation between sites of electron injection and hole transporting domains in the multinuclear complexes fails to enhance DSSC performance. Replacing Lancfflary 2 in [Cu(4) (2)](+) by the metalloligand Ru(bpy)(2)(2)}(2+) improves dye performance due to the better spectral response of the heteronuclear [Cu(4)(2)Ru(bpy)(2)}](3+) complex. This assembly approach presents a flexible method of tuning dye properties while retaining the surface-bound bis(diimine) copper(I) domain. (C) 2015 Elsevier Ltd. All rights reserved.

  A general synthetic methodology is reported for tris(bidentate)ruthenium(II) complexes containing three different polypyridyl ligands, based on the sequential addition of the ligands to the oligomer [Ru(CO)(2)Cl-2](n). The tris(heteroleptic) complexes were characterized by FAB mass spectrometry and NMR spectroscopy. An X-ray crystal structure determination was made for the complex, [Ru(Me(2)bpy)(phen)(bpa)](PF6)(2) . C6H14 [C40H43F12N7P2Ru, M = 1062.8; Me(2)bpy = 4,4'-dimethyl-2,2'-bipyridine, phen = 1,10-phenanthroline, bpa = bis(2-pyridyl)amine]: triclinic, space group , a = 14.57(3) Angstrom, b = 13.50(3) Angstrom, c = 12.73(3) Angstrom, alpha = 68.6(2)degrees, beta = 63.5(1)degrees, gamma = 79.8(2)degrees, V = 2082 Angstrom(3), Z = 2. Aspects of the electrochemistry, spectroscopy, and photophysics of the tris(heteroleptic) species are discussed.
