A trinuclear [[Ru(II)(bpy)(2)(bpy-terpy)](2)Fe(II)](6+) complex (I) in which a Fe(II)-bis-terpyridine-like centre is covalently linked to two Ru(II)-tris-bipyridine-like moieties by a bridging bipyridine-terpyridine ligand has been synthesised and characterised. Its electrochemical, photophysical and photochemical properties have been investigated in CH(3)CN and compared with those of mononucle...

The preparation and characterization of a new terpyridine molecule containing an acetylenic moiety is described. Part this molecule, unknown in the literature, obtained from biomass-derived synthon that formed naturally occurring syringaldehyde 4-hydroxy-3,5-dimethoxybenzaldehyde. title compound was fully characterized by NMR spectroscopy (1H 13C), as well high-resolution mass spectrometry infr...

Coordination-driven self-assembly of metal ions and organic ligands has been extensively applied over the past few decades, towards construction various functional two-dimensional (2D) three-dimensional (3D) architectures. The majority these structures are homoleptic in nature, consisting one type ligand. However, functionality self-assembled complexes can be potentially increased by increasing...

Six new complexes [Cd(tpy)(pfb)2] (1, tpy = 2,2?:6?,2?-terpyridine), [Ln2Cd2(tpy)2(pfb)10] (Ln Eu (2Eu), Tb (2Tb)), [Ln2Cd2(tbtpy)2(pfb)10]·2MeCN (3Eu), (3Tb), tbtpy 4,4?,4?-tri-tert-butyl-2,2?:6?,2?-terpyridine), [Eu2Cd2(tppz)(pfb)10]n (4, tppz 2,3,5,6-tetra-(pyridin-2-yl)pyrazine) based on pentafluorobenzoic acid (Hpfb) have been prepared and investigated. The effect of tridentate ligands geo...

Solution NMR studies of the interaction between the hexanucleotide d(GTCGAC)(2), β-cyclodextrin and a boronated 2,2':6',2''-terpyridineplatinum(II) complex containing 1,12-dicarba-closo-dodecaborane(12) (1,12-closo-carborane) reveal the formation of a remarkable ternary supramolecular system in which the terpyridine ligand is intercalated between the C(3) and G(4) bases, whilst the closo-carbor...

The title complex, [Er(C(15)H(11)O(2))(NO(3))(2)(C(18)H(15)N(3)O)]·CH(3)CN, has been synthesized from 4'-all-yloxy-2,2':6',2''-terpyridine (altpy), dibenzoyl-methane and erbium nitrate. The distorted monocapped square anti-prismatic coordination polyhedron is formed by a bidentate dibenzoyl-methanide residue, a tridentate altpy ligand and two nitrate anions that act as bidentate ligands and occ...

As a part of our recent studies of RNA cleavage using antisense oligonucleotide-metal complex(es) conjugates, we prepared self-complementary 2'-O-methyloligonucleotides with a terpyridine x Cu(II) complex, which was attached to the sugar portion of the 5'-end or 3'-end. The thermal stabilities of the formed duplexes, as compared with those of the unmodified 2'-O-methyl duplexes, revealed that b...

The synthesis of a perfluorocyclopentene based diarylethene bearing two terpyridine units is reported. Furthermore studies of the free ligand's photochromism and investigations regarding the influence of various transition metal ions on the photochromic reaction are presented. The photochromism of the central diarylethene unit is strongly dependent on the transition metal present, vice versa th...
