“…They are of particular interest since they allow the electronic, optical and catalytic properties of metal complexes to be incorporated within a polymer film that can be deposited in precise locations. A few metallopolymers with thiophene backbones have been described to date, and these include structures based on dithiolenes, 32-34 bithiophene-bithiazoles, 35 azaferrocenes 36 and terpyridines. 37, 38 To the best of our knowledge the reported metallopolymer is the first example with alkynethiolate units.…”

A series of alkynethiolate gold(I) derivatives have been synthesised by the cleavage of 4-monosubstituted 1,2,3-thiadiazoles in the presence of strong bases. The syntheses of the 1.2,3-thiadiazoles with p-cyanophenyl, p-tolyl, 2-thienyl, 3-thienyl and 9,9-dimethylfluoren-2-yl fragments are also described. All the complexes have been characterised by spectroscopic techniques and the complexes [Au(p-CH3-C6H4-C[triple bond]C-S)PPh3], [Au(3-C4H3S-C[triple bond]C-S)PPh3] and PPN[Au(p-CH3-C6H4-C[triple bond]C-S)(C6F5)] by X-ray analysis. The electrochemically polymerizable mononuclear bis(alkynethiolate) gold(I) complex PPN[Au(3-C4H3S-C[triple bond]C-S)2] is also described, including its electropolymerization and electrochemical properties.

“…In contrast to our work, a similar type of outer-sphere metallopolymer with a Pt-[NCN] pincer was reported by Holliday et al They showed smooth growth of the film, but the platinum centers are in immediate contact with the polymer backbone. The reported electropolymerisable behavior of the Pt-[NCN] pincer metallopolymer is similar to inner-sphere metallopolymers, where the metal centers play a structural role allowing smooth film growth during the cyclic electropolymerization. ,,− …”

Conducting polymers consisting of metal-selective coordination units and a highly conductive backbone, so-called metallopolymers, are interesting materials exposing single atoms for photo/electrocatalysis and thus represent a potential low-cost alternative for bulk or nanoparticulate platinum group metals (PGMs). We synthesized and fully characterized an electropolymerisable monomer bearing a pendant terpyridine unit for the selective complexation of PGMs. Electrocatalytic tests of the resulting metallopolymer, poly-[(tThTerpy)PtCl]Cl, revealed activity both in the oxygen reduction reaction and hydrogen evolution reaction. Rotating disk experiments showed the direct four-electron reduction of molecular oxygen to water at low angular velocities of the rotating electrode. Furthermore, the fabrication of Pt metallopolymers proved to be simple, nonhazardous and versatile. This proof-of-concept opens up the possibility for developing future low-cost electro- and photocatalysts to replace current systems.

“…During the first cycle, the forward (anodic) scan gave a complex oxidation wave O 1 , which could be assigned to thiophene oxidation, [16] with at least two unresolved peaks. On reversing the scan, the reduction peaks R 3 and R 2 were observed.…”

= 4,4Ј-bipyridine (4); 4,4Ј-vinylenedipyridine (5)] complexes. The nuclear selectivity is conveniently controlled by the choice of the heterocyclic ligands or spacers. Both structural types 3 and 5 were confirmed by single-crystal X-ray crystallographic analyses. Their solution identities were established by positive-ion Electrospray Mass Spectrometry (ESMS). The electroactivities of these complexes were studied by cyclic voltammetry (CV). Continuous CV scans of 4 and 5 revealed variations in the redox waves
