two‐component supramolecular organogels based on multiple chemical interactions between percarboxylato‐ and peramino‐pillararenes are described. Mixing low concentration solutions (<1 % w/v) of decacarboxylato‐pillar[5]arene (1) with decaamino‐pillar[5]arenes (2 b–d) affords, rapidly and without heating, organogels displaying an exceptional combination of properties. These supramolecular organogels, the characteristics
描述了基于过羧基-芳基和过氨基-芳基芳烃之间的多种化学相互作用而合理设计的两组分超分子有机凝胶。将低浓度十足羧基立柱[5]芳烃(1)和十氨基立柱[5]芳烃(2 b – d)的溶液(<1%w / v)混合,可以快速且不加热地显示出有机凝胶的出色组合特性。这些超分子有机凝胶,其特性是可调谐的,被认为是触变性和热稳定的,具有Ť凝胶在某些情况下,该值超过嵌入溶剂的沸点。结果表明,在这些吸引人的柔软材料的凝胶化过程中,结构互补性和多价性都是重要的决定因素。
