摘要本文综述了有机染料与粘土矿物之间相互作用的几个方面，并介绍了基于这些组分的杂化材料的一些有趣的性质。它解释了染料/粘土矿物杂化系统（DCHS）的基本现象和物理性质，同时研究了粘土矿物在其中的作用。简要的历史使用染料作为工具的粘土研究和传统材料的基础上DCHS。异色性是指与染料分子聚集体形成有关的颜色变化现象，本文对它进行了详细的描述，并从不同的角度进行了分析。详细分析了DCHS的光活性、发光、光催化性能、光学各向异性和非线性光学性能。粘土矿物在共振能量转移、发光猝灭等物理现象的发生中起着重要作用，并可能影响各种反应，如染料分子的构象变化、光致变色、光致异构化、光敏化等光化学过程。本文还介绍了各种杂化材料的合成路线。简要概述了DCHS在粘土研究、化学和材料科学中的应用。
Abstract This review summarizes several aspects of the interactions between organic dyes and clay minerals, and presents some interesting properties of hybrid materials based on these components. It explains the basic phenomena and photophysical properties of dye/clay mineral hybrid systems (DCHS) while examining the role of clay minerals in them. A brief history of using dyes as tools for clay research and on traditional materials based on DCHS is presented. Metachromasy, the phenomenon of colour change related to the formation of dye molecular aggregates is described in detail and analysed from various perspectives. The properties of DCHS, including photoactivity, luminescence, photocatalytic properties, optical anisotropy and non-linear optical properties are analysed in detail. Clay minerals often play a significant role in the occurrence of specific photophysical phenomena such as resonance energy transfer and luminescence quenching and may influence various reactions, such as conformational changes in dye molecules, photochromism, photoisomerization, photosensitization and other photochemical processes. Routes to synthesize various types of hybrid materials are also described here. The relevance of DCHS for clay research, chemistry and materials science is summarized briefly.
