An electron donor-acceptor covalent organic framework (TTF-COF1) was constructed by the imine condensation of electron donor tetraformyl-tetrathiafulvalene (TTF-fo) and electron acceptor 2,6-diaminoanthraquinone (DAQ). TTF-COF1 has intramolecular charge transfer, offering capacitance of 752 F g(-1) at 1 A g(-1) and an energy density of 57 W h kg(-1) at a power density of 858 W kg(-1).
