Heptagon-containing distorted nanographenes are used as stoppers for the capping of a [2]rotaxane through a Michael-type addition reaction to vinyl sulfone groups. These curved aromatics are bulky enough to prevent the disassembly of the rotaxane but also give emissive and nonlinear (two-photon absorption and emission) optical properties to the structure.
含七边形的扭曲纳米石墨烯被用作封端剂，通过与乙烯基砜基团的迈克尔型加成反应来封端[2]轮烷。这些弯曲的芳烃体积足够大，可防止轮烷解体，同时还赋予该结构发光和非线性（双光子吸收和发射）光学性质。
