The present work describes the synthesis and characterization of hybrid materials based on β-cyclodextrin (β-CD) and cetyltrimethylammonium bromide (CTAB) intercalated into saponite (SAP) and a commercially available powder of anthocyanin dye, Crystal Red Grape (RG). The interactions between the organic dye guest and the organo-clay host were investigated by X-ray diffraction, thermogravimetric analysis, transmission electronic microscopy and ¹³C solid state nuclear magnetic resonance. The results support complex formation between β-CD and CTAB, their intercalation into the clay interlayer spaces or surface loading, and their interaction with RG (CTAB_SAP-RG, β-CD_SAP-RG and β-CD+CTAB_SAP-RG). The hybrid pigments formed exhibit different colors, enhanced stability against visible light irradiation and basic pH conditions. These hybrid pigments are environmentally friendly and can be promising candidates in different application fields.

本工作描述了基于β-环糊精（β-CD）和十六烷基三甲基溴化铵（CTAB）嵌入皂石（SAP）和市售花色苷染料结晶红葡萄（RG）的杂化材料的合成和表征。通过X射线衍射，热重分析，透射电子显微镜和¹³考察了有机染料客体与有机粘土主体之间的相互作用。C固态核磁共振。结果支持β-CD和CTAB之间的复合物形成，它们插入粘土层间空间或表面载荷以及它们与RG的相互作用（CTAB_SAP-RG，β-CD_SAP-RG和β-CD+ CTAB_SAP-RG）。形成的杂化颜料表现出不同的颜色，增强了对可见光照射和碱性pH条件的稳定性。这些杂化颜料对环境友好，可以成为不同应用领域的有前途的候选物。
