Covalent organic frameworks (COFs) are an emerging class of materials that organize and align organic semiconductors predictably. COF syntheses use reversible covalent bond-forming reactions to link molecular building blocks into periodic two-dimensional (2D) or three-dimensional networks. The 2D variants crystallize into layered structures containing stacked aromatic subunits ideal for interlayer exciton and charge transport. 2D COFs exhibit several desirable and unique features: The length and relative orientation of their linking groups determine the lattice structure, in contrast to the unpredictable packing of traditional organic semiconductors. Also, their permanent porosity provides a continuous, high surface area interface for additional functionalization. Our work synthesizing COFs as both polycrystalline powders and oriented thin films will be presented.
