Photoswitchable glycoligands targeting Pseudomonas aeruginosa LecA

Biofilm formation is one of main causes of bacterial antimicrobial resistance infections. It is known that the soluble lectins LecA and LecB, produced by Pseudomonas aeruginosa , play a key role in biofilm formation and lung infection. Bacterial…

Complete kinetic and photochemical characterization of the multi-step photochromic reaction of donor–acceptor Stenhouse adducts

Donor–acceptor Stenhouse adducts (DASA) are negative photochromic compounds exhibiting a multistep photoisomerization mechanism. Previous studies have described a first photoactivated step, followed by a thermally controlled one. This study…

Heptazine derivative bearing tetrazine capped arms: A new fluorescent and redox platform for reduced graphene oxide functionalization

We have synthesized the first example of a heptazine molecule bearing three arms, each of them functionalized by a tetrazine at the end. This new original molecule is redox active and fluorescent, benefiting from the energy transfer between the…

Histoire

De la chimie avant la chimie. Au fil des textiles minéralisés, du 16e au 20e siècle

L’identification graduelle des textiles archéologiques par les « antiquaires » de l’époque moderne (XVI-XVIIIe siècle) conduit à s’interroger sur l’histoire de la perception de ces vestiges. Cette histoire rejoint celle de la proto-chimie…

Palladium‐Catalyzed Indirect and Regioselective Phosphonation of Azobenzenes: Toward the Design of Water‐Soluble Photoswitches

An efficient palladium‐catalyzed ortho C−H acyloxylation of azobenzenes, allowing the introduction of the difunctionalised substituent, diethylphosphonoacetate, is reported. Thanks to the mild reaction conditions implemented, this regioselective…

Spatial distribution of the photopolymerization induced by localized surface plasmons: impact of the morphology of the Au nanoparticles

The analysis of the local distribution of the electric field, induced by localized surface plasmon resonance (LSPR), is crucial for selecting the morphology of gold nanoparticles (AuNPs) for specific applications. The reported study is based on an…
