Ultrathin π-conjugated two-dimensional (2D) polymers (C2P) have the potential to revolutionize semiconductor technologies because of their predicted high carrier transport attributes. Bulk 2D polymers, also called covalent organic frameworks, are generally unprocessable, and their exfoliation to ultrathin C2Ps has not been realized. We present a rational bottom-up design strategy to access ultrathin C2Ps with high crystallinity in solution by choosing appropriate monomers, linkage chemistry, and reaction conditions. The C2Ps exhibit high hole mobilities and allow broadband photodetection with impressive photoresponsivities.
