Abstract
Optical storage properties of azobenzene-functionalized liquid crystalline telomer B and telomer D were investigated by holographic measurements. Both of the telomers are linear with different molecular structures. Linearly and circularly polarized Ar
+
laser of 488 nm was used to inscribe holographic gratings on the telomer films prepared by spin coating from their solutions in THF. Higher diffraction efficiency was obtained from telomer B compared to telomer D under identical experimental conditions. This may be due to lower glass transition temperature and rigidity of structure of telomer B. Diffraction efficiencies of 9% and 4% were obtained from telomer B and telomer D film, respectively by irradiation of linearly polarized Ar
+
laser (200 mW/cm
2
) for 15 minutes. The stored information in telomer films was seemed to be stable for long time under dark at room temperature.
