Abstract The interlayer space of kaolinite was functionalized with an ionic liquid (1-(2-hydroxyethyl)-3-methylimidazolium chloride (IL1)) by controlling the amount of grafted organic cation. The strategy used was to co-intercalate the compound to be grafted and a non-reactive template. The template was an IL (1-(propyl)-3-methylimidazolium chloride (IL2)) capable of intercalating in the interlayer space of kaolinite, without being grafted. This template when intercalated covers certain grafting sites and prevents them from reaction with other chemical species present in the interlayer space. Physicochemical characterizations confirm that the presence of the template effectively reduces the amount of grafted IL. This phenomenon was observed through the decrease of the d001-value of the nanohybrid kaolinite (from 13.1 A to 9.6 A) and the increase of the amount of physisorbed water which occupies the vacant space resulting from the partial grafting of the IL. Multifunctional materials were prepared by intercalating dimethyl sulfoxide (DMSO) or by grafting triethanolamine (TEA) molecules in the vacant space, using simple synthesis procedures. Several multifunctional materials can be produced using this approach, the main caution being the judicious choice of reagents. These materials can find promising applications in catalysis and in molecular recognition systems.

高岭石层间空间多功能化的模板方法

摘要 通过控制接枝有机阳离子的量，用离子液体（1-（2-羟乙基）-3-甲基咪唑氯化物（IL1））对高岭石的层间空间进行了功能化。所使用的策略是将要接枝的化合物和非反应性模板共嵌入。模板是一种 IL（1-（丙基）-3-甲基咪唑氯化物（IL2）），能够嵌入高岭石的层间空间，无需接枝。该模板在插入时覆盖某些接枝位点，并防止它们与层间空间中存在的其他化学物质发生反应。物理化学特征证实模板的存在有效地减少了接枝的 IL 的量。通过纳米杂化高岭石的 d001 值（从 13.1 A 到 9. 6 A) 以及由于 IL 的部分接枝导致占据空位的物理吸附水量的增加。多功能材料是通过插入二甲基亚砜 (DMSO) 或通过在空位接枝三乙醇胺 (TEA) 分子，使用简单的合成程序来制备的。使用这种方法可以生产几种多功能材料，主要的注意事项是明智地选择试剂。这些材料可以在催化和分子识别系统中找到有前景的应用。使用这种方法可以生产几种多功能材料，主要的注意事项是明智地选择试剂。这些材料可以在催化和分子识别系统中找到有前景的应用。使用这种方法可以生产几种多功能材料，主要的注意事项是明智地选择试剂。这些材料可以在催化和分子识别系统中找到有前景的应用。
