Covalent organic frameworks (COFs) usually crystallize as insoluble powders and their processing for suitable devices has been thought to be limited. Here, it is demonstrated that COFs can be mechanically pressed into shaped objects having anisotropic ordering with preferred orientation between the hk0 and 00l crystallographic planes. Pellets prepared from bulk COF powders impregnated with LiClOdisplayed room temperature conductivity up to 0.26 mS cmand stability up to 10.0 V (vs. Li/Li). This outcome portends use of COFs as solid-state electrolytes in batteries.
