增强n型单壁碳纳米管（SWCNTs）的热电性能作为未来的热动力源是强烈期望的。在这里，我们报告了显着的同时增强热电性能的二次分子掺杂与corannulene。与芘作为平面参考物质对热电性能和电子自旋共振（ESR）谱的影响相比，我们证明了有效的抑制单壁碳纳米管骨架与corannulene n型掺杂后的化学氧化和热电性能的恶化与其自由基清除活性。
Enhancement of the thermoelectric properties of n-type single-walled carbon nanotubes (SWCNTs) as a future thermopower source is strongly desired. Herein, we report a remarkable simultaneous enhancement of the thermoelectric properties by secondary molecular doping with corannulene. Compared with the effect of pyrene as a planar reference substance on the thermoelectric properties and electron spin resonance (ESR) spectrum, we demonstrate efficient suppression of chemical oxidation of the SWCNT backbone with corannulene upon n-type doping and of deterioration of the thermoelectric properties associated with its radical scavenging activity.
