In this work, we report a universal surface-assisted oxidative polymerization strategy for wafer-scale fabrication of ultrathin two-dimensional conjugated microporous polymers (2D CMPs) on arbitrary substrates under ambient conditions. Three kinds of 2D CMPs with average thickness of 1.5-3.6 nm were prepared on SiO2/Si substrates by using carbazole based monomers. Moreover, 2D CMPs can be grown on reduced graphene oxide (rGO) substrate to construct large-area 2D CMP/rGO heterostructure. As a proof-of-concept demonstration, an organic vertical field-effect transistor based on 2D CMP/rGO heterostructures was fabricated, which exhibited typical p-type behavior with high reproducibility and on/off current ratio. Most importantly, the direct growth of large-area 2D CMPs on arbitrary substrates is compatible with the conventional processes in the semiconductor industry, and therefore is expected to expedite the development of 2D CMPs as building blocks for construction of practical electronic devices.
