Fig. 1: Successful strategy to obtain uniform semi-conducting 2D rectangles by living CDSA.

a Structures of the PCPV homopolymer and BCP and illustrations of the resulting 2D nanosheets and 1D nanofibers from the PCPVs. The green color in polymer chains indicates a P1 shell block, and the pink color in polymer chains indicates a P2 core block. b Illustration of strategies for producing uniform 2D rectangles by living CDSA.
