Significance
The living Suzuki–Miyaura catalyst-transfer polymerization (SCTP) is successfully
applied to achieve length-controlled armchair graphene nanoribbons (GNR). The SCTP-enabled
length control over the polymers is confirmed by the narrow polydispersity.
Comment
The armchair GNRs prepared via SCTP show both narrow dispersity and excellent yields.
The great potency of the method is demonstrated with the acquirement of different
polymer structures, including GNR block copolymers.
