Three-dimensional covalent organic frameworks (3D COFs) with a pcu topology have been obtained from distorted polycyclic aromatic hydrocarbons acting as triangular antiprismatic (D3d ) nodes. Such 3D COFs are six-fold interpenetrated as the result of interframework π-stacking, which enable charge transport properties that are not expected for 3D COFs.
Keywords: 3D covalent organic frameworks; charge transport; interpenetration; non-planar aromatics; polycyclic aromatic hydrocarbons.
