Oligopeptides bearing internal diacetylene units are shown to self-assemble in water into one-dimensional nanostructures and aligned macroscopic hydrogels. The diacetylene units can be photopolymerized into polydiacetylenes that run coincident to the nanostructure and noodle long axes, and the resulting nanostructures show evidence for ambipolar charge transport. This self-assembly, alignment and polymerization technique provides a rapid way to produce globally aligned collections of conjugated polymer chains.
具有内部二炔基单元的寡肽在水中自组装成一维纳米结构和取向的宏观水凝胶。二炔基单元可以光聚合形成与纳米结构和面条长轴一致的聚二炔，所得纳米结构表现出双极电荷输运的证据。这种自组装、取向和聚合技术为制备全局取向的共轭聚合物链提供了一种快速的方法。
