Abstract:
A process for producing polymer-supported metal nanoparticles involves confinement of metal nanoparticles in polymeric nanotubes or nanosheets in an aqueous environment using hydrophobic reactants. Metal nanoparticles supported in the polymeric nanotubes or nanosheets are substantially monodisperse and have an average particle size of 4 nm or less. The polymer-supported metal nanoparticles are useful in fuel cells, sensors, bioanalysis, biological labeling or semi-conductors, especially as catalysts.

Abstract:
Polymers exhibiting solubility, conjugation and microporosity are processable and useful for a variety of applications. The polymers comprise repeating units which are linked together to form rigid macromolecular structures which do not exhibit space-efficient packing. The polymers may comprise aromatic structures, e.g. fused aromatic structures and/or multiply bonded aromatic structures, and may comprise solubilising groups such as for example branched alkyl groups or siliyl groups.
