Optically transparent films of a liquid crystalline (LC) polymer with azobenzene mesogens, which has recently been exploited for reversible holographic information storage, have been studied using solid‐state NMR. The extent to which optically switching the dye with laser light affects the alignment of the LC matrix, a factor which could influence the performance of the materials in storage applications, is examined.
