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…

Optical Nonlinearity in (EDT-DSDTFVO) 2 ·FeBr 4 , an Intriguing Molecular Material with Metallic Conductivity, Magnetoresistance Effects, and Quadratic Nonlinear Optical Properties

The quadratic (∝ E2) nonlinear optical (NLO) properties of (EDT-DSDTFVO)2·FeBr4 have been investigated: an efficiency equal to 3−6 times that of urea in second-harmonic generation at 1.907 μm has been observed by a powder test, and an effective …

Sugars to control ligand shape in metal complexes: conformationally constrained glycoligands with a predetermination of stereochemistry and a structural control.

In coordination chemistry, ligand shape can be used to tune properties, such as metal selectivity, coordination number, electronic structure, redox potential, and metal center stereochemistry including coordination helicates formation, and also to…

Synthesis of organic nanoparticles in a 3D flow focusing microreactor

In this paper, we present the synthesis of organic nanocrystals in a 3D hydrodynamic focusing device through a non-solvent crystallization process. This microreactor was designed in order to control the supersaturation level, while manipulating…

Pi-stacking functionalization through micelles swelling : Application to the synthesis of single wall carbon nanotube/porphyrin complexes for energy transfer

We report on a new, original and efficient method for p-stacking functionalization of single-wall carbon nanotubes. This method is applied to the synthesis of a high-yield light-harvesting system combining single-wall carbon nanotubes and porphyrin…
