偶氮苯聚合物和低聚物显示有趣的表面浮雕功能时，用偏振激光照射。我们表明，通过原子力显微镜调查的侧链偶氮苯聚合物照射后，通过振幅掩模，大的峰值或沟槽的结果取决于聚合物的架构。已经观察到长距离的广泛质量传输，为纳米结构的容易复制铺平了道路。我们还表明，它是可能的存储微观图像的拓扑结构的聚合物只是通过偏振光照射。
Azobenzene polymers and oligomers show intriguing surface relief features when irradiated with polarized laser light. We show through atomic force microscopic investigation of side-chain azobenzene polymers after irradiation through an amplitude mask that large peaks or trenches result depending on the architecture of the polymer. Extensive mass transport over long distances has been observed, paving the way for easy replication of nanostructures. We also show that it is possible to store microscopic images as topographic features in the polymers just through polarized light irradiation.
