The reactions of the substituted 2,2':6,2''-terpyridine ligands, 4'-mesityl-2,2':6',2''-terpyridine (mesitylterpy) (1a), 4,4',4''-tri-tert-butyl-2,2':6',2''-terpyridine (tri-(t)Buterpy) (1b) and 4'-phenyl-2,2':6',2''-terpyridine (phenylterpy) (1c) with Grignard reagents were investigated. When half an equivalent of mesitylterpy or tri-(t)Buterpy were treated with MeMgBr in diethyl ether, the on...

Cobalt(II) complexes of terpyridine bases [Co(L)₂](ClO₄)₂ (1-3), where L is 4'-phenyl-2,2':6',2''-terpyridine (ph-tpy in 1), 4'-(9-anthracenyl)-2,2':6',2''-terpyridine (an-tpy in 2) and 4'-(1- pyrenyl)-2,2':6',2''-terpyridine (py-tpy in 3), are prepared and their photo-induced DNA and protein cleavage activity and photocytotoxic property in HeLa cells studied. The 1 : 2 electrolytic and three-e...

All-round performance: a donor–?–acceptor type push–pull arylene–vinylene conjugated terpyridine showing multifunctional properties of solvatochromism, vapochromism, piezofluorochromism and remarkable fluorescence sensing properties.

In this work, we report the electrochemical response of a family Co(II) complexes, [CoII(L)3]2+ and [CoII(L’)2]2+ (L = 2,2’-bipyridine, 1,10-phenanthroline, 3,4,7,8-tetramethyl-1,10-phenanthroline, 5,6-dimethyl-1,10-phenanthroline, 4,7-diphenyl-1,10-phenanthroline; L’ terpyridine 4-chloro-terpyridine), in presence absence CO2 order to understand role redox potential molecular structure on catal...

Selective complexation of metal ions represents a powerful tool for the development versatile supramolecular architectures. While research in field molecular devices and machinery is sophisticated, selective formation complexes not prevalent polymer chemistry. Thus, implementation orthogonal binding concepts into polymeric matrix presented. In this context, an end-functionalized poly(N-isopropy...

The reactions of CuBr(2) with pyridyl 2,2':6',2''-terpyridine ligands in methanol yielded four copper complexes under solvothermal conditions. The self-assembly processes were accompanied by designing bitopic precursor ligands and increasing the stoichiometric metal-ligand ratio. In the four resulting complexes, the pendant pyridyl groups of pyridylterpyridine were selectively in situ N-methyla...

The cationic complex in the title compound, [RuCl(C10H8N2)(C19H20N3O3P)]PF6·0.83CH3CN·0.17H2O, is a water-oxidation precatalyst functionalized for TiO2 attachment via terpyridine phospho-nate. The The Ru(II) atom in the complex has a distorted octa-hedral geometry due to the restricted bite angle [159.50 (18)°] of the terpyridyl ligand. The dihedral angle between the least-squares planes of the...

In our continued efforts in the synthesis of ruthenium(II) polypyridine complexes as potential dyes for use in varied applications, such as the dye-sensitized solar cells (DSSCs), this work particularly describes the synthesis, absorption spectrum, redox behavior and luminescence properties of a new homoleptic ruthenium(II) complex bearing a simple trans-2-methyl-2-butenoic acid functionality a...

Four structurally related iridium(III) and ruthenium(II) complexes bearing two polar terpyridyl-stilbene derived chromophores 4-(4-{2-[4-(methoxy)phenyl]ethenyl}phenyl)-2,2'-6',2''-terpyridine (ttpyeneanisole) and 4-(4-{2-[phenyl]ethenyl}phenyl)-2,2'-6',2''-terpyridine (tpystilbene) have been synthesised and characterised in the solid state and in solution. In the solid state, the dihedral angl...
