Co-immobilization of a Rh Catalyst and a Keggin Polyoxometalate in the UiO-67 Zr-Based Metal–Organic Framework: In Depth Structural Characterization and Photocatalytic Properties for CO2 Reduction

The Keggin-type polyoxometalate (POM) PW12O403– and the catalytic complex Cp*Rh(bpydc)Cl2 (bpydc = 2,2′-bipyridine-5,5′-dicarboxylic acid) were coimmobilized in the Zr(IV) based metal organic framework UiO-67. The POM is encapsulated within the…

Time-resolved fluorescence microscopy combined to Scanning ElectroChemical Microscopy (SECM): a new way to visualize photo-induced electron transfer quenching with an electrofluorochromic probe

The combination of Scanning Electrochemical Microscopy (SECM) and Time-Resolved Fluorescence Microscopy was successfully implemented to investigate the control of the fluorescence of a tetrazine derivative in solution according to its redox state, a…

Luminescent molecular switches based on dicationic P-doped Polycyclic Aromatic Hydrocarbons

We report the efficient synthesis of electron-acceptors based on cationic P-doped polycyclic aromatic hydrocarbons. In particular, exo-skeletal modifications of the p-core were performed and their effect on the optical and redox properties was…

In-place molecular preservation of cellulose in 5,000-year-old archaeological textiles

The understanding of fossilization mechanisms at the nanoscale remains extremely challenging despite its fundamental interest and its implications for paleontology, archaeology, geoscience, and environmental and material sciences. The mineralization…

Exciton Interactions, Excimer Formation, and [2π+2π] Photodimerization in Nonconjugated Curcuminoid‐BF 2 Dimers

We describe the synthesis of a series of covalently linked dimers of quadrupolar curcuminoid‐BF2 dyes and the detailed investigation of their solvent‐dependent spectroscopic and photophysical properties. In solvents of low polarity, intramolecular…

A new Devonian euthycarcinoid reveals the use of different respiratory strategies during the marine-to-terrestrial transition in the myriapod lineage

Myriapods were, together with arachnids, the earliest animals to occupy terrestrial ecosystems, by at least the Silurian. The origin of myriapods and their land colonization have long remained puzzling until euthycarcinoids, an extinct group of…

Oxidative conditions can lead to exceptional preservation through phosphatization

Exceptional preservation through phosphatization is primarily controlled by a reduction in pH, favoring the precipitation of apatite over that of calcite. Laboratory experiments have suggested that phosphatization results from anoxic decay. Here we…
