Abstract

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.
