A fully complementary tris(urea) receptor for phosphate and sulfate anions has been developed by mimicking the scaffold of terpyridine which shows very high affinities and selectivities toward the tetrahedral anions.

Substitution-inert, redox- and photo-active ruthenium(II) complexes based on 2,2',6',2''-terpyridine ligands were self-assembled into discrete supramolecular cages via coordination to palladium(II) centres and characterised by NMR, ESI-MS and X-ray crystallography.

A protonated Zn(II) complex with a terpyridine-containing pentaamine macrocycle catalyses ATP hydrolysis in the presence of a second metal ion, which acts as cofactor assisting the phosphoryl transfer from ATP to an amine group of the receptor.

The crystal structures of bis-[4'-(pyridin-4-yl)-2,2':6',2''-terpyridine]-man-gan-ese(II) bis-(hexa-fluorido-phosphate) monohydrate, [Mn(C20H14N4)2](PF6)2·H2O, (1), and bis-[4'-(pyridin-4-yl)-2,2':6',2''-terpyridine]-manganese(II) bis(hexa-fluorido-phosphate) acetone monosolvate, (2), [Mn(C20H14N4)2](PF6)2·CH3COCH3, are described. At 150 K, (1) and (2) have monoclinic (P21/c) and ortho-rhom-bic...

Diphosphate (pyrophosphate, PPi) is vital for organisms, and therefore its detection is of special importance. In this paper, one cadmium complex of terpyridine (tpy) derivative, 4'-(aminomethylphenyl)-2,2':6',2"-terpyridine (aptpy), has been reported for the ratiometric fluorescence recognition of PPi. When added with cadmium, the emission of aptpy at 358 nm was greatly enhanced and red shifte...

Cyclic brush polymers represent an exciting new macromolecular topology. For the first time, this new topology has been combined with metallo-supramolecular interactions to construct novel cyclic brush polymers. Here, ring-expansion metathesis polymerization was used to synthesize a universal cyclic template with a polynorbornene backbone, which was further modified with the metal-chelating syn...

The reaction between [Pt(terpy)Cl]·2H(2)O (terpy = 2',2'':6',2''-terpyridine) and 1-methyl-imidazole (MIm) in the presence of two equivalents of AgClO(4) in nitro-methane yields the title compound, [Pt(C(15)H(11)N(3))(C(4)H(6)N(2))](ClO(4))(2)·CH(3)NO(2). The dicationic complexes are arranged in a staggered configuration. The torsion angle subtended by the 1-methyl-imidazole ring relative to th...

The synthesis and photophysical properties of a new terpyridine-based europium(III) chelate (Eu (TMT)-AP3) designed for peptide and protein labelling in aqueous solution phase is described. In order to obtain a stable, easy to handle, versatile and efficient labelling agent, a reactive aminopropargyl arm has been introduced onto the terpyridine moiety. As preliminary biochemical applications th...

Dramatic improvements in ribozyme mimics have been achieved by employing the principles of small molecule catalysis to the design of macromolecular, biomimetic reagents. Ribozyme mimics derived from the ligand 2,9-dimethylphenanthroline (neocuproine) show at least 30-fold improvements in efficiency at sequence-specific RNA cleavage when compared with analogous o-phenanthroline- and terpyridine-...

Pressure, Electrode Potential, Reaction Volumes Pressure dependence of the electrode potentials for various M3+/2+ couples (M = Fe, Co, and Ni with o-phenanthroline, bipyridine, terpyridine, 1,4,7-triazacyclononane, and 1,4,7-trithiacyclononane) was measured by cyclic voltammetry in aqueous solution vs. a Ag/AgCl reference electrode. The reaction volume of the Ag/AgCl reference electrode was es...
