Abstract: Heteroaromatic-conjugated aromatic molecules have inspired numerous interests in rechargeable batteries like Li-ion batteries, but were limited by low conductivity and easy dissolution in electrolytes. Herein, we immobilize a nitrogen-rich aromatic molecule tricycloquinazoline (TQ) and CuO 4 unit into a two-dimensional (2D) conductive Metal-Organic Framework (MOF) to unlock their potential for Li + storage. TQ was identified redox activity with Li + for the first time. With a synergistic effect of TQ and CuO 4 unit, the 2D conductive MOF, named Cu-HHTQ (HHTQ = 2,3,7,8,12,13-hexahydroxytricycloquinazoline), can facilitate the Li + /e - transport and ensure a resilient electrode, resulting in a high capacity of 657.6 mAh g -1 at 600 mA g -1 with extraordinary high-rate capability and impressive cyclability. Our findings highlight an efficient strategy of constructing electrode materials for energy storage with combining multiple redox-active moieties into conductive MOFs.
