In this paper, the authors use a photo-catalyzed Diels-Alder reaction (between a photoenol and an olefin) to make tri-block copolymers with PDI~1.2. The central block was made using ADMET for a selective head-to-tail polymerization, resulting hetero- end-functional polymers. The photocatalyzed Diels-Alder reaction is highly selective and efficient, and allowed for a one-pot synthesis of the tri-block copolymers.
