Photocatalytic function of a polymer-supported B12 complex with a ruthenium trisbipyridine photosensitizer.

A polymerized ionic liquid-supported B12 catalyst with a ruthenium trisbipyridine photosensitizer for photocatalytic dechlorination in ionic liquids.

By immobilizing a B12 complex and a Ru(ii) trisbipyridine photosensitizer in a polymerized ionic liquid (PIL), a visible light-driven photocatalyst was developed. The synthesized copolymer was characterized by GPC and DLS, and using UV-vis absorption spectra and luminescence spectra. The Ru(ii) trisbipyridine photosensitizer in the copolymer showed an enhanced emission compared to that of the m...

Photocatalytic Oxidation of Water by Silica-Supported Tris(4,4′-dialkyl-2,2′-bipyridyl)ruthenium Polymeric Sensitizers and Colloidal Iridium Oxide

A cationic polymer containing tris(4,4′-dialkyl-2,2′-bipyridyl)ruthenium groups linked by aliphatic spacers was studied as a photosensitizer for the catalytic oxidation of water in the presence of colloidal IrO2. The polymer-colloidal IrO2 system photocatalytically reduced persulfate, a sacrificial electron acceptor, and oxidized water to O2 and H+ in solutions that were buffered at pH 6 by Na2...

Synthesis and Photophysical Properties of Ruthenium Trisbipyridine Functionalized Gold Nanoparticles

Influence of polystyrenesulfonate on electron transfer quenching of ruthenium trisbipyridine luminescence by viologens: non-covalent assembly and covalent tethering of the ruthenium complexw

A new copolymer (RuB-PSS) of ruthenium(II)bis-(2,20-bipyridine)(4-vinyl 2,20-bipyridine) and styrene sulfonate was prepared which tethers the ruthenium chromophore directly to the polymer backbone. The photophysical properties of the copolymer, and its luminescence quenching by viologens, were compared with those of ruthenium(II)tris-bipyridine, [Ru(bpy)3] , bound non-covalently to polystyrenes...

Construction of a supported Ru complex on bifunctional MOF-253 for photocatalytic CO2 reduction under visible light.

A MOF-253 supported active Ru carbonyl complex (MOF-253-Ru(CO)2Cl2) was constructed for photocatalytic CO2 reduction under visible light irradiation. Its performance can be further improved by immobilization as a photosensitizer. This study highlights the great potential of using MOFs as a solid ligand and platform for the assembly of a complicated catalytic system.
