Chimie organique

General Route to Symmetric and Asymmetric meso-CF(3)-3(5)-Aryl(hetaryl)- and 3,5-Diaryl(dihetaryl)-BODIPY Dyes.

A general efficient route to hitherto inaccessible symmetric and asymmetric meso-CF(3)-BODIPY dyes has been developed. The key stages include the reduction of available 2-trifluoroacetylpyrroles to the corresponding alcohols which are further…

Synthesis and Biological Evaluation of 4′-C,3′-O-Propylene-Linked Bicyclic Nucleosides

A set of pyrimidine nucleosides fused with a 4'-C,3'-O-propylene bridge was successfully synthesised in 12 steps from 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose, an inexpensive starting material, based on a ring-closing metathesis (RCM)…

Design of blue or yellow emitting devices controlled by the deposition process of a cationic iridium (III) complex

A phosphorescent cyclometalated heteroleptic Ir(III) complex was investigated as emitter for light-emitting electrochemical cells (LECs) and polymer organic light-emitting diodes (POLEDs). By exploring the deposition conditions of the emissive layer…

One-Pot Synthesis of Pegylated Fluorescent Nanoparticles by RAFT Miniemulsion Polymerization Using a Phase Inversion Process.

Water-soluble and fluorescent core-shell nanoparticles (FNP) are synthesized in a miniemulsion reversible addition-fragmentation transfer (RAFT) polymerization and are shown to respond to pH. The particles are obtained from a hydrophilic PEO-b-PAA…

Investigating the possible use of a tetra (hydroxyphenyl) porphyrin as a fluorescence probe for the supramolecular detection of phospholipids

The present work explores the interest of using the 5,10,15,20-tetrakis(3-hydroxyphenyl)- 21H,23H-porphin (m-THPP), a commercially available porphyrin, as a polarity probe for the detection of phospholipids. Feasibility of the process was first…

Fullerene-functionalized carbon nanotubes as improved optical limiting devices

We report the synthesis, characterization and optical limiting behavior of a nanohybrid built by grafting C60-fullerenes on carbon nanotubes (CNTs). The nonlinear optical limiting properties of the CNT-C60 complex were investigated at wavelengths…
