Abstract

Abstract Dendrons composed of three functionalized cone calix [4] arene substructures covalently bound to rigid C 3-symmetric tris-anilino cores through amide linkages have been obtained by a divergent synthetic protocol involving the coupling of p-nitrocalix [4] arene butanoic acid 9 with tris (4-aminophenyl) amine (TAPA), 1, 3, 5-tris (4-aminophenyl) benzene (TAPB), and 2, 4, 6-tris (4-aminophenyl)-s-triazine (TAPT). Two different ...
