隐色染料表示与具有长链部分的酸性化合物（称为显影剂）的可逆着色反应。为了阐明该体系在着色态和脱色态之间的结构变化，进行了X射线衍射（XRD）测量和透射电子显微镜（TEM）观察。结果表明，隐色染料与显色剂的混合物在着色和脱色状态下呈现不同的层状结构。这种结构变化表明无色染料在可逆着色过程中发生了嵌入和脱嵌。提出了长链分子对隐色染料的显色/脱色反应机理。(c)2007 Elsevier B. V.保留所有权利。
Leuco dye indicates the reversible coloring reaction with acidic compounds (called developer) having long-chain moiety. In order to clarify the structural change between colored state and decolored one of this system, X-ray diffraction (XRD) measurements and transmission electron microscope (TEM) observations were performed. It was found that mixture of leuco dye and developer took different layered structures between colored and decolored state. This structural change shows intercalation and deintercalation of leuco dye occur in the reversible coloring process. The mechanism of coloring/decoloring reaction of leuco dye with long-chain molecule is proposed. (c) 2007 Elsevier B.V. All rights reserved.
