The syntheses of calix[4]arene dimelamines that are functionalized with alkyl, aminoalkyl, ureido, pyridyl, carbohydrate, amino acid and peptide functionalities, and their self-assembly with barbituric acid or cyanuric acid derivatives into well-defined hydrogen-bonded nanostructures are described. The thermodynamic stability of these hydrogen-bonded assemblies was studied by CD spectroscopy in mixtures of CHCl3 and MeOH. The stability of the assemblies depends on several steric factors and the polarity of the functional groups connected to the assembly components.
用烷基、氨基烷基、脲基、吡啶基、碳水化合物、氨基酸和肽官能团官能化的杯[4]芳烃二三聚氰胺的合成,以及它们与巴比妥酸或氰尿酸衍生物的自组装成明确的氢键纳米结构描述的。通过 CD 光谱在 CHCl3 和 MeOH 混合物中研究了这些氢键组装体的热力学稳定性。组件的稳定性取决于几个空间因素以及连接到组件组件的官能团的极性。
