Absract Iron-copper complexes have been extensively studied in the search for efficient cytochrome c oxidase models. Whereas most dinuclear materials usually focus on fine-tuning the coordination of heme-Fe, this work shows that the coordination of copper in cytochrome c oxidase models should be…
Abstract The discovery of a stable organic radical formed under mild, clean, and efficient light-mediated conditions is reported. The structure of the stable acridinium-based radical photoproduct was unambiguously established by single-crystal X-ray diffraction, mass spectrometry, and in solution…

Abstract Winning combo: Porphyrins and polyoxometalates can be combined into useful architectures for energy conversion, this minireview highlights the most successful strategies developed to date.
Summary A series of porphyrin dimers have been prepared and characterized in order to form inclusion complexes with Lindqvist-type polyoxometallates. The synthesis of the porphyrin dimer has been optimized and can serve general purposes. The formation of inclusion complexes has been monitored using…
Abstract : Recent reports have identified Cp*Co-based complexes to be powerful catalysts for aromatic C–H bond activation under oxidative conditions. However, little is known about the speciation of Cp*Co species during catalysis. We now show that key intermediates, Cp*CoIII metallacycles derived…
Abstract The introduction of nanoparticles (MNPs) at the surface of cationic poly-porphyrin films, obtained by electrostatic interaction between the bis-porphyrin copolymer and the Preyssler type polyoxometalate P5W30@MNPs, enhances the photocurrent (up to 2.5-3 times greater as a function of the…
Abstract Four hybrid polyoxometalate–porphyrin copolymer films were obtained by the electrooxidation of zinc-β-octaethylporphyrin (ZnOEP) or 5,15-ditolylporphyrin (H2T2P) in the presence of organosilyl functionalized Keggin-type POMs TBA3[PW11Si2O40C26H16N2] (abbreviated Py-PW11Si2-Py) and…
Abstract Two novel polyoxovanadate-iodoBodipy supramolecular assemblies, named as (2I-BDP-C6)2V6 and (2I-BDP-C6)3V10, were first synthesized by self-assembly of anionic hexavanadate and decavanadate with cationic iodoBodipy for photochemotherapy, respectively. The mechanisms for synergistic…
Abstract A new green synthetic route to tris[4‐(3,4‐ethylenedioxythiophene)phenyl]amine (TEPA) monomer has been developed and the molecular structure of TEPA has been determined by using single‐crystal XRD. Solution‐processable nanoporous poly{tris[4‐(3,4‐ethylenedioxythiophene)phenyl]amine}…
Abstract Iron-containing sludges (DW/Fe) were prepared by the electroflocculation of industrial printing and dyeing wastewater (DW). To investigate the formation process and the properties of the DW/Fe sludges and their application in anode materials in Li-ion batteries, the DW/Fe sludges were…
Abstract Nickel is a very abundant transition metal in the Earth's crust, and it finds numerous applications in electrochemical processes where metallic Ni or its oxides are thermodynamically stable, particularly in alkaline environments. This contribution addresses electrocatalytic properties of…
Abstract A series of three new polyoxometalate/spiromolecule compounds – including the (TBA)3[AlMo6-SN] (SN = spironaphthoxazine) and (TBA)3[AlMo6-SP] (SP = spiropyran) Anderson-type polyoxometalates (POMs) and the unprecedented (TBA)5[P2W15V3-SP] Dawson-type species – has been synthesized and…
Abstract Functionalization of a methylviologen with four methyl ester substituents significantly facilitates the first two reduction steps. The easily generated radical cation shows markedly improved air stability compared to the parent methylviologen, making this derivative of interest in organic…
