    Abstract
    Covalent organic frameworks (COFs) are a novel class of porous crystalline organic materials assembled from molecular building blocks. Due to their high surface area and ability to precisely control electro-active groups in their pores, COFs have emerged as an ideal candidate for energy storage devices. Here we present a two dimensional (2D) COF with redox active pyridine units that exhibit reversible electrochemical processes. When used as an electrode in supercapacitors, this redox COF shows faradaic behavior and excellent chemical stability even after 6000 charge–discharge cycles. This strategy may shed light on designing ...

    Covalent organic frameworks (COFs) are a novel class of porous crystalline organic materials assembled from molecular building blocks. Due to their high surface area and ability to precisely control electro-active groups in their pores, COFs have emerged as an ideal candidate for energy storage devices. Here we present a two dimensional (2D) COF with redox active pyridine units that exhibit reversible electrochemical processes. When used as an electrode in supercapacitors, this redox COF shows faradaic behavior and excellent chemical stability even after 6000 charge–discharge cycles. This strategy may shed light on designing new redox active COF based faradaic supercapacitors and other electrochemical devices.
