Nanoparticles functionalized polymer with

A new class of metal-loaded nanoparticles was developed by Reynolds et al. (95). These materials have a core-shell morphology, where the core is a functionalized polymer with a high affinity to the Gd(III) ions. The core polymer contained monomers with carboxylate pendant arms, such as ethylacrylate, methacrylate, butylacrylate or allylmethacrylate. The shell consisted of a... 

Research on semiconductor nanoparticle technology by chemists, materials scientists, and physicists has already led to the fabrication of a number of devices. Initially, Alivisatos and co-workers developed an electroluminescence device from a dispersion of CdSe nanoparticles capped with a conducting polymer349 and then improved on this by replacing the polymer with a layer of CdS, producing a device with efficiency and lifetime increased by factors of 8 and 10, respectively. 0 Chemical synthetic methods for the assembly of nanocrystal composites, consisting of II-VI quantum dot polymer composite materials,351 represent one important step towards the fabrication of new functional devices that incorporate quantum dots. 

Hyperbranched PEI or functionalized PEIs with glycidol (PEI-GLY), glu-conolactone (PEI-GLU) or lactobionic acid (PEI-LAC) have been used as support materials for metal nanoparticles in water. Polymer-stabilized metal nanoparticles were prepared in a two-step process. After complexation of the metal ions with the respective polymer in a first step, a chemical reduction with sodium borohydride was performed in a second step to obtain the metal... 

Nanocomposites based on polymers and nanoparticles (NPs) are diverse and versatile functional materials, with applications ranging from electronic device fabrication to biosensors and catalysis [1-7]. The controllable polymer chain length, tunable NP size and core materials, and various side-chain and ligand functionahzation enable these macromolecular building blocks... 

This article has been focussing on poly(phenylene)s with 1,4-(para-)phenylene units since these polymers play a key role in the synthesis-driven search for electronic materials. From this article it has become clear that poly(phenylene) chemistry has not restricted its attention to linear (ID-) structures, but has more recently developed into 2D- and 3D-structures as well, the latter serving as functional shape-persistent nanoparticles. 

The living ROMP reactions of norbornene and norbornene derivatives have been used to make a variety of polymers possessing unusual properties. Copolymerization of selected functionalized norbornenes with norbornene has been used to synthesize star polymers and side-chain liquid crystal polymers. " This chemistry has also resulted in the preparation of phase separated block copolymers that contain uniform sized metal or semiconductor nanoparticles. The... 

MMA, and St from magnetite nanoparticles functionalized with an organophosphono initiator, was reported by Babu and Dhamodharan [107c]. Mesoporous hybrid materials made of mesoporous silica and a covalently grafted polymer with controlled chain length were successfully synthesized by surface-initiated ATRP of St and MMA [107d].
