摘要

Stable metal-organic frameworks (MOFs) with the required functions have unique advantages in practical applications. Herein, we studied the electrochemical property of a stable zirconium-based MOF, Zr₆(μ₃-O)₄(μ₃-OH)₄(OH)₆(H₂O)₆(HCHC) (PCN-136), which contains a hexacarboxylate linker with a π-conjugated nanographene moiety (HCHC = hexakis(4-carboxyphenyl)hexabenzocoronene). In light of the high chemical stability and π-conjugated nanographene moiety, PCN-136 exhibits a specific capacitance of 694 F g⁻¹ at the current density of 0.5 A g⁻¹ in a 6 M KOH aqueous solution. PCN-136 holds great potential as a high-performance capacitive material for electrochemical energy storage.
