以聚四氟乙烯(PTFE)薄膜为基材，在玻璃板上进行机械摩擦。聚四氟乙烯薄膜是由沿滑动方向有少量凹槽的高度取向的薄层组成。与晶体c轴对应的聚四氟乙烯大分子的链轴平行于玻璃表面。沉积在聚四氟乙烯涂层玻璃板上的双乙炔分子，如4，6-Decadiyn-1，10-diol-bis-(n-butoxycarbonyl-methyl-urethane)，沿着聚四氟乙烯薄膜的凹槽形成盘状或长方形的微晶。二乙炔分子几乎垂直于衬底表面吸附其侧链，并沿聚四氟乙烯大分子的链轴排列
Polytetrafluoroethylene (PTFE) thin film used as substrates was rubbed mechanically on a glass plate. PTFE thin film was composed of a highly oriented thin layer containing a few grooves along the sliding direction. The chain axis of the PTFE macromolecules corresponding to the crystal c-axis was oriented parallel to the glass surface. Diacetylene molecules such as 4,6- decadiyn- 1,10-diol-bis-(n-butoxycarbonyl-methyl-urethane) deposited on a PTFE-coated glass plate formed disk-like or rectangular crystallites along the grooves of the PTFE film. Diacetylene molecules adsorbed their side chains almost perpendicular to the substrate surface and were aligned along the chain axis of the PTFE macromolecules
