通过阴离子苝衍生物的pi堆叠，实现了氮化硼纳米管（BNNTs）在水溶液中的非共价功能化，首次制备了羧酸功能化BNNTs。从功能化纳米管出发，设计并演示了一种用于纳米碳纳米管近表面可控碳掺杂的创新方法。由于这种精细的掺杂，新型的B-C-N/BN同轴纳米管被制备出来，并通过门相关输运测量阐明了它们的p型半导体行为。
Noncovalent functionalization of boron nitride nanotubes (BNNTs) in aqueous solution was achieved by means of pi-stacking of an anionic perylene derivative, through which carboxylate-functionalized BNNTs were prepared for the first time. Starting from the functionalized nanotubes, an innovative methodology was designed and demonstrated for the controlled near-surface carbon doping of BNNTs. As a result of such delicate doping, novel B-C-N/BN coaxial nanotubes have been fabricated, and their p-type semiconducting behaviors were elucidated through gate-dependent transport measurements.
