Abstract
A new facile method of synthesis of calix[4]arene amide via the aminolysis of the calix[4]arene esters was reported. One ethyl ester of the compound ( 2) was aminolysized by n-butylamine. The crystal structure of compound (1) shows that one ethyl ester of compound (1) enters into the cavity of anothe r compound (1) forming a long chain host-guest supramolecule. From the 2D N MR data, the compound (1) does not assemble in THF or CHCl3 solution. The C H-pi interaction and crystallization energy might be the important driving forces for forming the self-assembled calix[4]arene.
