3D COFs with pcu topology are obtained from distorted polycyclic aromatic hydrocarbons acting as triangular antiprismatic (D-3d) nodes. These 3D COFs exhibit six-fold interpenetration due to interframework pi-stacking, leading to unexpected charge transport properties.
Three-dimensional covalent organic frameworks (3D COFs) with a pcu topology have been obtained from distorted polycyclic aromatic hydrocarbons acting as triangular antiprismatic (D-3d) nodes. Such 3D COFs are six-fold interpenetrated as the result of interframework pi-stacking, which enable charge transport properties that are not expected for 3D COFs.
