## Abstract New polydimethylsiloxanes with __p__‐substituted azobenzene side‐groups were synthesized. Thin films and solutions exhibit a photochemical __trans‐cis__ isomerization of the azobenzene groups, followed by their __cis‐trans__ thermal relaxation in the dark. In films, relaxation rates wer
