Efficient Light Activation of a [Ru(bpy)(tpy)Cl]+ Catalyst by a Porphyrin Photosensitizer at Small Driving Force

SSRN Electronic Journal (2020)

Athanassios G. Coutsolelos Georgios Charalambidis Asterios Charisiadis Sofia Margiola Athanassios G. Coutsolelos

Light activation of dyads containing porphyrins and a catalytic ruthenium complex having a high oxidation potential (~1 V vs SCE) is investigated by time-resolved spectroscopy. It is shown that activation of the ruthenium complex occurs through oxidative quenching of the chromophore in the presence of a reversible electron acceptor. Despite the lack of driving force for intramolecular electron transfer, an efficient intramolecular oxidation of the catalyst is observed, suggesting that porphyrins are attractive chromophores to activate oxidation catalysts throughout the visible spectrum.

Aqueous–Organic Biphasic Hydrogenation of trans‐Cinnamaldehyde Catalyzed by Rhodium and Ruthenium Phosphane‐Free Porphyrin Complexes

European Journal of Inorganic Chemistry (2011)

Christina Stangel Georgios Charalambidis Varvara Varda Athanassios G. Coutsolelos Ioannis D. Kostas

Abstract The synthesis and spectroscopic characterization of new rhodium and ruthenium complexes with a porphyrin, possessing carboxylic groups in the arms of the porphyrin ring, is described. The complexes are completely soluble in water in the presence of a base (KOH or triethylamine). These phosphane‐free and air‐stable complexes were evaluated as catalysts in the aqueous hydrogenation of trans ‐cinnamaldehyde. Catalysis was more efficient with the ammonium salts of the complexes rather than the corresponding potassium carboxylate salts, preferably in water/toluene rather than in neat water. The effect of catalyst concentration, reaction temperature, hydrogen pressure and methanol addition on the catalytic activity of the complexes in the presence of triethylamine in an aqueous–organic biphasic system was investigated. The catalysts were presumably homogeneous, and could be recycled and reused without any significant difference in activity and selectivity. This is the first time that porphyrin–metal complexes have been used as catalysts for hydrogenation of α,β‐unsaturated aldehydes.

Cascades of energy and electron transfer in a panchromatic absorber

Nanoscale (2022)

Jan Joseph Stefan Bauroth Asterios Charisiadis Georgios Charalambidis Athanassios G. Coutsolelos

The investigation of molecular model systems is fundamental towards a deeper understanding of key photochemical steps in natural photosynthesis. Herein, we report an entirely non-covalent triad consisting of boron dipyrromethene (BDP), porphyrin (ZnP), and fullerene (C60). Non-covalent binding motifs such as an amidinium-carboxylate salt bridge as well as axial pyridyl-metal coordination offer substantial electronic coupling and establish efficient pathways for photoactivated energy and electron transfer processes along a well-tuned gradient. Experimental findings from steady-state and time-resolved spectroscopic assays, as well as (spectro-)electrochemical measurements corroborate the formation of BDP|ZnP|C60 in solution, on one hand, and significant communication in the excited states, on the other hand. BDP acts as an energy harvesting antenna towards ZnP, which eventually undergoes charge separation with C60 by electron transfer from ZnP to C60. Notably, full spectral deconvolution of the transient species was achieved, supporting the successful self-assembly as well as giving a clear view onto the occurring photophysical processes and their spectral footprints upon photoexcitation.
