両親媒性カリックス[4]レゾルシンアレーンの複合体形成について

抄録

In this study, complex formation of an amphiphilic cyclic compound, calix[4]resorcinarene (CR) with amines are reported. CR with 4 alkyl chains of 10 carbon atoms (CR(10)) were prepared by condensation of resorcinol and undecanal under acidic condition. CR(10) formed complexes with amines in ethanol. The complex formation is facilitated by hydrogen bonds between hydroxyl groups and amino groups. The complexes showed different thermal stability depending on the kind of amines. The complex obtained from CR(10) and diamines retained the structure in the molten state and until decomposition of CR(10). However, the complex obtained from CR(10) and monoamines decomposed to CR(10) and monoamines before the melting point of the complex. The thermal stability of the complexes depends on the number of amino groups that interact.
