From Eilatin to Isoeilatin:  A Skeletal Rearrangement Strongly Influences π-Stacking of Ru(II) Complex

Abstract

The C(1)-symmetrical complex [Ru(bpy)(2)(ieil)][PF(6)](2) exhibits unique electrochemical and photophysical properties, and forms discrete dimers in solution and in the solid state held by weak pi-pi stacking interactions via its isoeilatin ligand, preferentially from one of its faces and in a specific orientation.

Supramolecular activation of a molecular photocatalyst

“…7 The planar ligand structure has previously been utilized for detailed dimerization studies of the related mononuclear ruthenium complex [Ru(bpy) 2 (tpphz)](PF 6 ) 2 in solution. [29][30][31][32][33] More recently the DNA intercalation of tpphz-based Ru complexes has been utilized to access reversible luminescent switches.…”

A Modular Approach to Luminescent Dinuclear Ruthenium(II) and Rhenium(I) Complexes

“…[3] Initially concentrated on the ubiquitous [Ru(bpy) 3 ] 2+ motif, [4,5] the family of photoactive transition metals has extended to include the analogous osmium complexes, [6][7][8][9] the acetylene complexes of platinum [10] and the cyclometallated benzopyridine complexes of iridium(III). [11] Interest in (bipyridyl)tricarbonylrhenium(I) complexes has given rise to a wealth of new luminescent materials [12] with potential application in metal-mediated photo-induced reduction of carbon dioxide [13][14][15] and sensing devices.…”

Different complexation behavior of a proton transfer compound obtained from 1,10-phenanthroline and pyridine-2,6-dicarboxylic acid with InIII and CeIII: Synthesis, crystal structures and solution studies

“…We have particularly aimed to investigate 'hydrogen bonding' interactions, which have received a special interest in different fields because of their directional and precise nature [17][18][19][20]. We have also regarded the 'p-p stacking' interaction as a remarkable feature of some of our crystalline systems, as it has been considered as an effective factor on stability of biological and chemical systems [21][22][23][24][25]. Some of interesting metal complexes in which the noncovalent interactions play important roles in creation of the crystalline networks, were obtained from the proton transfer compound LH 2 , (phenH) 2 (pydc) (phenZ1,10-phenanthroline), that was reported by our research group previously [26].…”
