【摘要】 <正>The diameter and chiral angle of a single-walled carbon nanotube（SWCNT） jointly determine its chiral indices（n, m）, which consequently dictate its properties. Theoretical predictions suggest that SWCNTs with extremely small diameters exhibit strong electron–phonon coupling [1], potentially leading to intriguing properties such as superconductivity and high fluorescence quantum yield. Early attempts synthesized 0.4 nm SWCNT arrays within zeolite AlPO4-5 channels by pyrolyzing tripropylamine molecules in a vacuum of 10-4Torr [2]. However, the significant curvaturestrain energy renders these SWCNTs inherently unstable. Upon extraction from the channels, these unstable SWCNTs transform into graphite fragments, hindering the exploration of their intrinsic properties free from zeolite interference and potential applications[2]. Experimentally,（5, 4） nanotubes（0.61 nm in diameter） are the smallest stable tubular structures identified to date that can withstand rigorous processing procedures [3,4].更多还原
