N2 - Quadruply fused aromatic heterocycles are examined as 4 V-class organic cathode-active materials. A newly synthesized dimethylfluoflavin-substituted polymer displays reversible charge/discharge at high potentials of 3.5 and 4.1 V (vs. Li/Li+) as a cathode-active material for organic secondary batteries. The robust redox-active heterocycles enable the long cycle-life (>1000) while maintaining the high potential over 4 V. The linear polymer backbone and radical spin configuration in the heterocycles are the keys to enhancing the voltages and the cycle life.
