Multiarm star polystyrene (PS) with pentafluorophenyl and allyl moieties at the periphery is prepared through the cross-linking reaction of α-fluoro and α-allyl functionalized PS and divinyl benzene (DVB) yielding (fluoro-PS)m–polyDVB–(allyl-PS)m multiarm star polymer. Orthogonal thiol-para-fluoro and photoinduced radical thiol-ene double “click” reactions are successfully employed for the postfunctionalization of the obtained star polymer.
