“…In this study, a novel quinone-enriched CMP was synthesized through a modified Diels–Alder reaction. − Characterization results and model reactions indicated that the proposed Diels–Alder reaction is feasible for CMP synthesis. Because of the rigid fused backbone and the substantial CO groups, when used as a LIB cathode, the as-prepared CMP exhibited excellent electrochemical characteristics, including a high lithium-ion diffusion coefficient (5.30 × 10 –11 cm 2 s –1 ) and long-term cyclability (a 94.8% capacity retention at a high current density of 1.0 A g –1 after 1500 cycles).…”

Among various organic cathode materials, CO group-enriched structures have attracted wide attention worldwide. However, small organic molecules have long suffered from dissolving in electrolytes during charge–discharge cycles. π-Conjugated microporous polymers (CMPs) become one solution to address this issue. However, the synthesis strategy for CMPs with rich CO groups and stable backbones remains a challenge. In this study, a novel CMP enriched with CO units was synthesized through a highly efficient Diels–Alder reaction. The as-prepared CMP exhibited a fused carbon backbone and a semiconductive characteristic with a band gap of 1.4 eV. When used as an organic electrode material in LIBs, the insoluble and robust fused structure caused such CMPs to exhibit remarkable cycling stability (a 96.1% capacity retention at 0.2 A g–1 after 200 cycles and a 94.8% capacity retention at 1 A g–1 after 1500 cycles), superior lithium-ion diffusion coefficient (5.30 × 10–11 cm2 s–1), and excellent rate capability (95.8 mAh g–1 at 1 A g–1). This study provided a novel synthetic method for fabricating quinone-enriched fused CMPs, which can be used as LIB cathode materials.
