Photochromic behaviors of hemithioindigo (HT) derivatives in bilayermembrane matrices and related aqueous system are investigated. HT derivatives were incorporated into bilayermembrane matrices at a molar ratio to bilayer amphiphiles of 0.01. Under these conditions, HT amphiphiles having an ammonio group disperse molecularly in the array bilayermembranes, and show the simple photochromism as in
研究了半硫靛 (HT) 衍生物在双层膜基质和相关水系统中的光致变色行为。HT 衍生物以与双层两亲物的摩尔比为 0.01 并入双层膜基质中。在这些条件下,具有氨基的 HT 两亲物分子分散在阵列双层膜中,并显示出与有机溶液中一样的简单光致变色。另一方面,对于不具有亲水基团的 HT 衍生物,除了光致变色反应之外,还进行不可逆的光漂白,这可能是双层膜中簇形成的结果。光稳态下的 E 型转化和 E 到 Z 热异构化速率在很大程度上受双层基质的晶体到液晶相变的影响。
