Moreover , azo dyes find wide applicability in reversible optical data storage . the storage process utilizes the light induced trans - cis - trans isomerization of the azo dye , thereby utilizing the local variation of the refractive index of the medium 另外,偶氮類染料在可逆的光信息存儲(全息和數字)得到廣泛應用,存儲過程就是利用光致偶氮類染料的反式?順式?反式的異構化過程,從而利用介質折射率的局部變化來進行存儲。
A kind of chiral azo molecule derived from amino acid , n - [ 4 - ( 4 - dodecyloxyphenylazo ) benzoyl ] - l - glutamic acid ( c12 - azo - l - glu ) , was investigated . the photochromism , photoinduced birefringence , and holographic recording in c12 - azo - l - glu doped poly ( methyl methacrylate ) ( pmma ) films were studied . c12 - azo - l - glu underwent a reversible tram - cis - trans isomerization in the polymer matrix 我們利用手性偶氮苯染料c _ ( 12 ) - azo - l - glu摻雜聚甲基丙稀酸甲脂( pmma )薄膜為實驗樣品,對其光致變色過程,光致雙折射和全息存儲特性進行了研究分析。
