Redox-active covalent organic frameworks (COFs) are promising materials for energy storage devices because of their high d. of redox sites, permanent and controlled porosity, high surface areas, and tunable structures. However, the low electrochem. accessibility of their redox-active sites has limited COF-based devices either to thin films (<250 nm) grown on conductive substrates or to thicker films (1 μm) when a conductive polymer is introduced into the COF pores. Elec. energy storage devices constructed from bulk microcrystalline COF powders, eliminating the need for both thin-film formation and conductive polymer guests, would offer both improved capacity and potentially scalable fabrication processes. Here we report on the synthesis and electrochem. evaluation of a new phenazine-based 2D COF (DAPH-TFP COF), as well as its composite with poly(3,4-ethylenedioxythiophene) (PEDOT). Both the COF and its PEDOT composite were evaluated as powders that were solution-cast onto bulk electrodes serving as current collectors. The unmodified DAPH-TFP COF exhibited excellent elec. access to its redox sites, even without PEDOT functionalization, and outperformed the PEDOT composite of our previously reported anthraquinone-based system. Devices containing DAPH-TFP COF were able to deliver both high-energy and high-power densities, validating the promise of unmodified redox-active COFs that are easily incorporated into elec. energy storage devices. In addition to this study using 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde, there are many other studies that have used 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Formula: C9H6O6) was used in this study.
2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4) is a member of phloroglucinol derivatives. Regarding monomeric phloroglucinols, this group encompasses acryl phloroglucinols, phloroglucinol-terpene adducts, phloroglucinol glycosides, halogenated phloroglucinols, prenylated phloroglucinols, and cyclicroup polyketides.Formula: C9H6O6
