New polymer synthesis by nitroxide mediated living radical polymerizations.
Preparation of polymers with controlled molecular architecture. A new convergent approach to dendritic macromolecules
The novel convergent growth approach to topological macromolecules based on dendritic fragments is described. The polyether dendritic fragments are prepared by starting from what will become the… Expand
Interdiffusion of PCBM and P3HT Reveals Miscibility in a Photovoltaically Active Blend
Developing a better understanding of the evolution of morphology in plastic solar cells is the key to designing new materials and structures that achieve photoconversion efficiencies greater than… Expand
Controlling Polymer-Surface Interactions with Random Copolymer Brushes
A simple technique for precisely controlling the interfacial energies and wetting behavior of polymers in contact with solid surfaces is described. End-functionalized statistical random copolymers of… Expand
Controlled Synthesis of Polymer Brushes by “Living” Free Radical Polymerization Techniques
The preparation of a wide variety of unique polymer brush structures can be accomplished by “living” free radical polymerization of vinyl monomers from surface-tethered alkoxyamines or from tethered… Expand
Unimolecular micelles and globular amphiphiles: dendritic macromolecules as novel recyclable solubilization agents
The synthesis of dendritic polyether macromolecules based on a 3, 5-dihydroxybenzyl alcohol building block and having carboxylate groups as chain-ends is described. These novel macromolecules behave… Expand

A novel approach is presented for the controlled intramolecular collapse of linear polymer chains to give well-defined single-molecule nanoparticles whose structure is directly related to the… Expand
Efficiency and fidelity in a click-chemistry route to triazole dendrimers by the copper(i)-catalyzed ligation of azides and alkynes.
General Strategies for Nanoparticle Dispersion
Traditionally the dispersion of particles in polymeric materials has proven difficult and frequently results in phase separation and agglomeration. We show that thermodynamically stable dispersion of… Expand
