Ring-opening metathesis polymerization (ROMP) of buckybowl corannulene-based oxa-norbornadiene monomer is shown to give rise to polymeric nanomaterials with an average pore size of about 1.4 nm and a surface area of 49.2 m2/g. Application in supercapacitor devices show that the corannulene-based nanomaterials exhibit a specific capacitance of 134 F·g–1 (1.0 V voltage window) in a three-electrode cell configuration. Moreover, the electrode assembled from these materials in a symmetric configuration (1.6 V voltage window) exhibits long-term cyclability of 90% capacitance retention after undergoing 10000 cycles. This work demonstrates that ROMP is a valuable method in synthesizing nanostructured corannulene polymers, and that materials based on the nonplanar polycyclic aromatic motif represents an attractive active component for fabrication of devices targeted at electrochemical energy storage applications.

基于 Buckybowl 基序的聚合物纳米材料：通过开环复分解聚合合成和储能应用
buckybowl corannulene 基氧杂降冰片二烯单体的开环复分解聚合 (ROMP) 可产生平均孔径约为 1.4 nm 和表面积为 49.2 m 2 /g 的聚合物纳米材料。在超级电容器器件中的应用表明，基于corannulene 的纳米材料的比电容为134 F·g –1（1.0 V 电压窗口）在三电极电池配置中。此外，由这些材料以对称配置（1.6 V 电压窗口）组装而成的电极在经历 10000 次循环后表现出 90% 电容保持率的长期循环性。这项工作表明，ROMP 是一种合成纳米结构的corannulene 聚合物的有价值的方法，并且基于非平面多环芳族基序的材料代表了用于制造针对电化学储能应用的设备的有吸引力的活性成分。
