Photoreduction of triplet thioxanthone derivative by azolium tetraphenylborate: a way to photogenerate N-heterocyclic carbenes

Although N-heterocyclic carbenes (NHCs) have brought profound changes in catalytic organic synthesis, their generation generally requires an inert atmosphere and harsh conditions. To overcome these limitations, an air-stable NHC photogenerator has…

New TBT based conducting polymers functionalized with redox-active tetrazines

We describe the synthesis of two new polymerizable monomers, and the subsequent polymers functionalized by tetrazine pendant groups, along with their electrochemical behaviour and fluorescence properties. In all cases a very stable conducting…

Multivalent Recognition at Fluid Surfaces: The Interplay of Receptor Clustering and Superselectivity

The interaction between a biological membrane and its environment is a complex process, as it involves multivalent binding between ligand/receptor pairs, which can self-organise in patches. Any description of the specific binding of biomolecules to…

Dual Light and Redox Control of NIR Luminescence with Complementary Photochromic and Organometallic Antennae

With the help of a judicious association between dithienylethene (DTE) units, an ytterbium ion, and a ruthenium carbon-rich complex, we describe (i) the efficient (on/off) switching of pure NIR luminescence with a photochromic unit absorbing in the…

Optimization of aggregation-induced phosphorescence enhancement in mononuclear tricarbonyl rhenium(I) complexes: the influence of steric hindrance and isomerism

In order to improve the remarkable performance of a mononuclear tricarbonyl rhenium(I) complex (ReL1) that exhibits rare aggregation-induced phosphorescence enhancement (AIPE) behavior, two new complexes (ReL3 and ReL4) were prepared and…

Combined SECM-fluorescence microscopy using a water-soluble electrofluorochromic dye as the redox mediator

A combined experiment of fluorescence and electrochemical microscopies was performed to highlight the possibility of using a unique water-soluble molecule as the redox mediator and fluorescence reporter. Resorufin was selected as it owns a highly…

Mechano-responsive circularly polarized luminescence of organic solid-state chiral emitters

Two difluoro-boron b-diketonate complexes bearing chiral amido groups have been synthesized. Their mechano-responsive luminescence and chiroptical properties have been investigated in the solid state. Both compounds display a bright blue-green…

Fluorescence microscopy visualization of the roughness-induced transition between lubrication regimes

We investigate the transition between different regimes of lubrication and directly observe the thickness of nanometric lubrication films with a sensitivity of a single molecular layer at a multi-asperity interface through fluorescence microscopy…
