This study presents the intercalation into Layered Double Hydroxides (LDHs) of two sulfonated organic molecules featuring the mesoionic triazolium scaffold. These sulfonated fluorophores exhibited excellent solubility in aqueous basic solutions, facilitating their compatibility with the synthesis of LDHs through coprecipitation methods. We applied the size-matching interlayer space (SMIS) approach by substituting a portion of a mono- or dianionic surfactant used in LDH preparation by the sulfonated fluorophore, we aimed to match the size of the luminescent interleaved guest effectively. Our investigation focused on two anion spacers: the classic monoanionic dodecyl sulfate (DS) and the dianionic phenylene dipropionate (PPA). Our results indicated that the latter spacer allowed a more efficient insertion of the fluorescent guest. Thermal resistance analysis underscored the robustness of the final hybrid materials, suggesting a promising design strategy for luminescent materials when applied in diverse applications.

嵌入层状双氢氧化物中的三唑基荧光团：从简单合成到明亮的固态发光

本研究提出了两种以介离子三唑支架为特征的磺化有机分子嵌入层状双氢氧化物（LDH）中。这些磺化荧光团在碱性水溶液中表现出优异的溶解度，有助于它们与通过共沉淀方法合成 LDH 的相容性。我们应用尺寸匹配层间空间（SMIS）方法，通过用磺化荧光团取代LDH制备中使用的部分单阴离子或双阴离子表面活性剂，我们的目标是有效匹配发光交错客体的尺寸。我们的研究集中在两种阴离子间隔基上：经典的单阴离子十二烷基硫酸盐 (DS) 和双阴离子亚苯基二丙酸酯 (PPA)。我们的结果表明，后一个间隔基可以更有效地插入荧光客体。热阻分析强调了最终混合材料的稳健性，为发光材料在不同应用中的应用提供了一种有前途的设计策略。
