“…“Click” reactions, defined as high‐yielding reactions under benign conditions,10 have recently been the subject of concerted scientific attention and typically fall into five categories: the azide‐alkyne cycloaddition,11 the thiol‐ene,12 thiol‐yne,13 thiol‐icocyanate,14 and the RAFT‐hetero‐Diels‐Alder reactions 15. There have been numerous reports of the use of RAFT in conjunction with click chemistry as a route towards surface modification16–24 and while the azide‐alkyne click reaction has been the most employed click reaction by far, several groups have recently been studying isocyanate‐bearing moieties as ideal candidates for click reactions due to their ability to react quantitatively with alcohols, thiols, and amines under mild reaction conditions 14, 25–30. In these reactions, the isocyanate functionality is incorporated into the polymeric backbone either by homopolymerizing an isocyanate‐bearing monomer, or by copolymerizing it along with another monomer 14, 25, 28–38.…”
