用原子力显微镜观察了聚二苯乙炔的螺旋结构，发现其具有旋光取代基，通过酰胺键连接，并具有螺旋度记忆。聚合物自组装成一个有序的2D单层高度取向的热解石墨暴露于溶剂蒸气后，其螺距和手性（右手和左手）的第一次直接揭示在分子分辨率。
The helical structures of poly(diphenylacetylene)s bearing optically active substituents linked through amide bonds and with a helicity memory have been visualised using atomic force microscopy. The polymers self-assembled into an ordered 2D monolayer on highly oriented pyrolytic graphite upon exposure to solvent vapour, whose helical pitch and handedness (right- and left-handed) were for the first time directly revealed at molecular resolution.
