质子化形式的改性3,5-二吡咯基吡唑(DPP)衍生物与三氟乙酸根(TFA)离子形成平面[2+2]型络合物。这些复合物作为离子对组装体的组成成分。基于这些[2+2]-型复合物构建尺寸控制的有组织结构的一个基本策略是引入带有长烷基链的芳环,这使得能够在界面、超分子凝胶和中间相形成2D图案。
Modified 3,5‐dipyrrolylpyrazole (DPP) derivatives in their protonated form produce planar [2+2]‐type complexes with trifluoroacetate (TFA) ions. These complexes serve as constituent components of ion‐pair‐based assemblies. An essential strategy for the construction of dimension‐controlled organized structures based on these [2+2]‐type complexes is the introduction of aryl rings bearing long alkyl chains, which enables the formation of 2D patterns at interfaces, supramolecular gels, and mesophases.
