description

We describe the preparation of LB-films of novel polymers containing azobenzene dye side chains. X-ray refection measurements, surface-plasmon experiments were used to determine the structure of LB-films which had been transferred onto a substrate. Illumination with UV-light causes trans-cis isomerisation of the azobenzene side groups. This effect can be used for optical data storage and will be discussed in detail.
