Green, scalable and morphology controlled synthesis of nanofibrous covalent organic frameworks and their nanohybrids through a vapor-assisted solid-state approach

Here we demonstrate a novel solid-state approach for the facile, green and scalable synthesis of covalent organic frameworks (COFs) in the presence of relatively small amounts of solvent vapors. Rarely observed uniform nanofibrous morphologies could be obtained through fine-tuning the solvent composition. When graphene oxide was added, hierarchically 1D–2D graphene oxide based nanohybrids could be obtained.
