We investigate the dispersion mechanisms of nanocomposites made well-defined polymer (polystyrene, PS) grafted-nanoparticles (silica) mixed with free chains same using a combination scattering (SAXS/USAXS) and imaging (TEM) techniques. show that relevant parameter dispersion, grafted/free mass ratio R tuned specific synthesis process, enables to manage arrangement grafted nanoparticles inside matrix either as large compact aggregates (R < 0.24) or individual > 0.24). From analysis...
Light–emitting Electrochemical Cells (LECs) constitute one of the most recent generations Organic Light–Emitting Diodes (OLEDs). The main difference between LECs and OLEDs is that include mobile ions in active layer. Ionic transition–metal complexes especially ionic iridium (III) have recently attracted widespread attention as potential electroluminescent materials for LECs. Herein, we present an overview incorporating phosphorescent emitters. Synthetic strategies developed to introduce...

We present a new convenient and efficient 'grafting-from' method to obtain well-defined polystyrene (PS) silica nanoparticles. The method, based on nitroxide-mediated polymerization (NMP), consists of binding covalently the alkoxyamine (which acts as an initiator controlling agent) nanoparticles surface in two steps. first step is reaction between aminopropylsilane particles order functionalize particle with amino group. In second step, initiation-controlling moiety introduced via...
Abstract The synthesis of two random copolymers bearing pendant mixed‐ligand orthometallated terpyridine‐based cationic iridium (III) complexes, as well their uses single‐layered electrophosphorescent emitters in polymer light‐emitting diodes is described. Both solution‐processable metallopolymers are prepared by copolymerization styrene with a complex‐substituted nitroxide mediated polymerization. Results on devices based used dopant poly( N ‐vinylcarbazole) or alone single layers...
We synthesized well-defined polystyrene-grafted silica nanoparticles by adapting our previous synthesis process without using free initiator. were able to obtain a more versatile system in which we can tune the masses of grafted chains while controlling polymerization, colloidal stability and avoid formation polymer chains. The final objects characterized refined way SANS contrast matching method.
