Hydrophobicity/hydrophilicity tunable hyperbranched polystyrenes as novel supports for transition-metal nanoparticlesElectronic supplementary information (ESI) available. See DOI: 10.1039/c2cc35390c

Development of a new preparative procedure for hyperbranched polystyrene having Cl end groups (HPS-Cl) enables to prepare HPS-NR 3 + Cl − , for which the hydrophobicity/hydrophilicity is tunable by the R groups. The resulting ammonium salts behave as a good support of platinum nanoparticles, which is useful for catalytic biphasic hydrogenation of alkenes. A new preparative procedure for hyperbranched polystyrene having Cl end groups enables the preparation of HPS-NR 3 + Cl − , which behaves as a good support for Pt NPs for biphasic hydrogenation of alkenes.
