Reported is a macrocyclic diacetylene that assembled into columns to afford porous crystals. Heating this assembly initiated a topochemical polymerization of the preorganized diacetylene units to give covalent conjugated polydiacetylenes. These stable conjugated materials maintained permanent porosity as evidenced by their type I gas adsorption isotherms with CO(2) (g). Such conjugated polymeric nanotubes could possess unusual properties for sensing and electronics.
报道了一种大环二乙炔,它组装成柱状结构,形成多孔晶体。加热这种组装体引发预组织二乙炔单元的拓扑化学聚合,得到共价共轭聚二乙炔。这些稳定的共轭材料保持着永久的多孔性,这一点可以从它们与 CO(2)(g)的 I 型气体吸附等温线上得到证明。这种共轭聚合物纳米管可能具有用于传感和电子学的特殊性质。
