摘要:

In this paper, different optical methods which lead to orientation or translation of several photochromes in polymer matrices are discussed. These methods lead to dichroic or birefringent, or nonlinear optically active materials or to stable surface gratings. They have mainly been demonstrated for azobenzene-type photochromes, but some of these effects also occur for other kinds of photochromes like spiropyrans, fulgides or diarylethenes.
