trimethylsiloxymethylene- and pentafluorophenoxymethylene-) as well as with an additional azobenzene unit were successfully obtained. The photoisomerization behaviors of the synthesized azo dyes were investigated in solution as well as in films. Importantly, the occurrence of photoisomerization (at least near the surface after UV treatment) was confirmed in the crystalline dye films. The resulting compounds can be
合成了一系列基于4-苯基偶氮苯酚的反应性偶氮染料,其中含有己烯氧基,烯丙氧基-乙氧基-丙氧基和四甲基-二硅氧烷基-丙氧基取代基。此外,成功地获得了具有可变分离基团(羟基亚甲基,三甲基甲硅烷氧基亚甲基和五氟苯氧基亚甲基)以及附加的偶氮苯单元的烯丙基官能化基于偶氮的发色团。研究了合成的偶氮染料在溶液和薄膜中的光异构行为。重要的是,在结晶染料膜中确认了光异构化的发生(至少在UV处理后的表面附近)。所得化合物可用于合成多种适用于光学和电光学应用的基于偶氮的材料。
