The Wittig reaction is demonstrated as novel synthetic strategy for the synthesis of crystalline unsubstituted vinylene-linked 2D conjugated covalent organic frameworks through the attainment of high (E)-alkene selectivity. Ultrafast THz spectroscopy discloses state-of-the-art charge-transport properties of as-prepared V-2D-COFs as a result of electron delocalization in the fully conjugated frameworks.
