Dual modification of a triple-stranded β-helix nanotube with Ru and Re metal complexes to promote photocatalytic reduction of CO2.

چکیده
We have constructed a robust β-helical nanotube from the component proteins of bacteriophage T4 and modified this nanotube with Ru(II)(bpy)(3) and Re(I)(bpy)(CO)(3)Cl complexes. The photocatalytic system arranged on the tube catalyzes the reduction of CO(2) with higher reactivity than that of the mixture of the monomeric forms.

We developed new cyclic Re(I)-based trinuclear redox photosensitizers with both high oxidation power in the excited state and strong reduction power in the reduced form. These excellent properties were achieved by introducing electron-donating groups on the diimine ligand of the Re(I) metal centre and by connecting each Re(I) unit with polyphenyl–bisphosphine bridging ligands. These Re-rings we...
متن کاملArchitecture of supramolecular metal complexes for photocatalytic CO2 reduction: ruthenium-rhenium bi- and tetranuclear complexes.
We study the electrochemical, spectroscopic, and photocatalytic properties of a series of Ru(II)-Re(I) binuclear complexes linked by bridging ligands 1,3-bis(4'-methyl-[2,2']bipyridinyl-4-yl)propan-2-ol (bpyC3bpy) and 4-methyl-4'-[1,10]phenanthroline-[5,6-d]imidazol-2-yl)bipyridine (mfibpy) and a tetranuclear complex in which three [Re(CO)3Cl] moieties are coordinated to the central Ru using th...
متن کاملA Visible-Light Harvesting System for CO2 Reduction Using a RuII–ReI Photocatalyst Adsorbed in Mesoporous Organosilica
A photocatalytic system for CO2 reduction exhibiting visible-light harvesting was developed by preparing a hybrid consisting of a supramolecular metal complex as photocatalyst and periodic mesoporous organosilica (PMO) as light harvester. A Ru(II) Re(I) binuclear complex (RuRe) with methylphosphonic acid anchor groups was adsorbed on acridone or methylacridone embedded in the walls of PMO mes...
متن کاملPhotochemical reduction of CO2 with ascorbate in aqueous solution using vesicles acting as photocatalysts.
We report a novel system of visible-light-driven CO2 reduction to CO in an aqueous solution, in which DPPC vesicles dispersed in the solution act as a photocatalyst using ascorbate (HAsc(-)) as an electron source. In the vesicles metal complexes [Ru(dtb)(bpy)2](2+) and Re(dtb)(CO)3Cl (dtb = 4,4'-ditridecyl-2,2'-bipyridyl) are incorporated, which act as a photosensitizer and a catalyst for CO2 r...

The photocatalytic activity for CO(2) reduction and optical and electrochemical properties of two Ru(II)-Re(I) binuclear complexes [Ru(dmb)(2)LRe(CO)(3)Cl](2+) (Ru-Re and Ru=Re, dmb = 4,4'-dimethyl-2,2'-bipyridine) with 1,2-bis(4'-methyl-2,2'-bipyridyl-4-yl)ethane and 1,2-bis(4'-methyl-2,2'-bipyridyl-4-yl)ethene as bridging ligands have been investigated. The conjugation content of the bridging...
