AimTo investigate the efficacy of thiol-yne nucleophilic click reactions for the synthesis of functional amphiphilic polymers with high densities of functional groups.

MethodExperimental synthesis and characterization of polymers.

ProcedureMonomers with electron-deficient alkyne groups were polymerized using RAFT polymerization. The alkyne groups on the polymer side chains were then reacted with thiol reagents via nucleophilic click chemistry, first with triethylamine and subsequently with a stronger base (TBD) to attach multiple functionalities. A second polymerization strategy involved reacting bi-functional thiol monomers with activated alkyne termini.
