The synthesis of a metal–organic framework (MOF) named IITI‐1 is reported by employing an H 2 L linker with Cu(NO 3 ) 2 ⋅3 H 2 O in a mixed solvent system of N , N ‐dimethyl formamide (DMF) and H 2 O. Further, in order to explore the energy storage application of IITI‐1 , a IITI‐1/CNT hybrid was prepared by a simple ultrasonication technique. Incorporation of a carbon nanotube (CNT) in the layered IITI‐1 MOF gave rise to enhanced electrolyte accessibility along with improved electrochemical storage capacity. The electrochemical investigations reveal a high specific capacitance (380 F g −1 at 1.6 A g −1 ) with a good rate performance for IITI‐1/CNT . The IITI‐1 MOF and the IITI‐1/CNT composite were characterized by PXRD, BET, SEM, and TEM techniques. Moreover, IITI‐1 MOF was also confirmed by single‐crystal XRD analysis.
