Versatile and Controlled Functionalization of Polyferrocenylsilane-b-Polyvinylsiloxane Block Copolymers Using a N-hydroxysuccinimidyl Ester Strategy

A general route for the N-hydroxysuccinimidyl (NHS) ester functionalization of poly(ferrocenyldimethylsilane)-b-polyvinylsiloxane copolymers, which should be readily transferrable to other vinyl containing polymers, has been developed using a simple two step approach. Facile reaction of the NHS ester functionalized polymers with primary amines enables the incorporation of a range of functionalities previously inaccessible using standard thiol-ene click reactions.
