A poly(2-vinylpyridine)-block-poly(2-(4-vinylphenyl)pyridine) (P2VP106-b-PVPPy95) coil-coil diblock copolymer forms hollow flower micelles in a mixed solvent of methanol and water (95/5, v/v) in a one step process. The geometry and composition of the micelles allow formation of a Pt-Au bimetallic dendritic nanocatalyst with a Pt leaf at room temperature.

A simple strategy to tailor the surface of nanoparticles for their specific adsorption to and localization at block copolymer interfaces was explored. Gold nanoparticles coated by a mixture of low molecular weight thiol end-functional polystyrene (PS-SH) (Mn = 1.5 and 3.4 kg/mol) and poly(2-vinylpyridine) homopolymers (P2VP-SH) (Mn = 1.5 and 3.0 kg/mol) were incorporated into a lamellar poly(st...

Poly(vinylpyridine oxides) in pneumo-coniosis research. Schlipkoter and Brockhaus of the Institut fur Lufthygiene Dusseldorf found that poly(2-vinylpyridine 1-oxide) can inhibit the fibrosis normally produced by quartz dust in the lungs or other tissues of animals. Later research in Germany and elsewhere has confirmed the earlier observations. The polymer is active when the quartz is administer...

In the crystal structure of the title compound, C(6)H(6)N(3) (+)·C(6)H(2)N(3)O(7) (-), anions and cations are linked into chains along [010] by inter-molecular N-H⋯O hydrogen bonds. These chains are further stabilized by weak C-H⋯O hydrogen bonds and π-π stacking inter-actions with a centroid-centroid distance of 3.908 (1) Å.

Polymerization-induced formation of amphiphilic diblock copolymer vesicles is performed in water at high concentrations by a single-step nitroxide-mediated controlled free-radical emulsion polymerization of 4-vinylpyridine, initiated by a water-soluble poly(sodium acrylate) macroalkoxyamine at alkaline pH.

Pt-decorated mesoporous silica is directly prepared using a polymeric micelles assembly approach using an asymmetric triblock copolymer, poly(styrene-b-2-vinylpyridine-b-ethylene oxide) as the structure directing agent. Strongly immobilized, fully accessible, and uniformly dispersed Pt nanoparticles on mesoporous silica wall exhibit superior catalytic activity toward CO oxidation.
