A strategy for sequence control in vinyl polymers via iterative controlled radical cyclization.

Nat. Commun. 7 , 11064, (2016)

There is a growing interest in sequence-controlled polymers toward advanced functional materials. However, control of side-chain order for vinyl polymers has been lacking feasibility in the field of p...
