Photochromism and Holographic Recording in Polymer Film Containing Azobenzene Molecules
|
Abstract:
A kind of azobeneze molecule,(E)-6-(4-((4-(octadecyloxy)phenyl)diazenyl)phenoxy)hexan-1-ol(E-1-ol),was synthesized,which was doped into poly(methyl methacrylate)(PMMA)films as light storage material.The photochromism,photoinduced birefringence,and holographic recording properties in the PMMA films containing E-1-ol were studied.The E-1-ol underwent a reversible trans-cis-trans isomerization in the polymer matrix.The photoinduced birefringence was investigated at various recording beam intensities of Ar+ las...
