文摘

We propose a concept of supramolecular materials for effective all-optical generation of surface reliefstructures and optical anisotropy. The materials are based on the ionic interactions between photochromicazobenzene units and polyelectrolytes. The materials are easy to produce and they allow the inscriptionof the 1.8 mages/entities/mgr.gif">m deep surface relief gratings. Moreover, the induced structures were thermally very stable.Both distinctive features of the new materials, namely, the dynamic behavior of molecular orientationand the high thermal stability of surface structures, have been explained in terms of the network ofoppositely charged ions inherent to the materials. Due to the simplicity and versatility of the concept, thenew family of materials for different applications in optics, sensorics, and biology may be designed.
