制备了具有亚纳米孔径（0.8nm）的新型聚芳分子管。在外周上具有六个磺酸酯基团并且在开口处具有十二个甲氧基基团的管提供了具有类似于1.3nm的长度的圆柱形疏水腔。该水性管可以定量地结合一分子的烃类客体在水中，伴随着客体诱导的发射增强（最多类似于3倍）的主机框架。
New polyaromatic molecular tubes with a subnanometer pore (0.8 nm) were prepared. The tube bearing six sulfonate groups on the periphery and twelve methoxy groups at the openings provides a cylindrical hydrophobic cavity with a length of similar to 1.3 nm. The aqueous tube can quantitatively bind one molecule of hydrocarbon guests in water with accompanying guest-induced emission enhancement (up to similar to 3 times) of the host framework.
