| Several calix[4]arene derivatives propylated on the lower rim and substituted on the upper rim with various groups have been synthesized. Examples include C-linked-alaninocalix[4]arene, N-linked-alaninocalix[4]arene, anilinocalix[4]arene, amidinocalix[4]arene, aminomethylcalix[4]arene, and carboxycalix[4]arene. Some calix[4]arene derivatives disubstituted on the upper rim in the 1,3 and 2,4 pattern have also been synthesized such as, di-C-linked-glycinodicarboxycalix[4]arene and di-N-linked-glycinodianilinocalix[4]arene along with larger chain amino acids such as beta-alanine and gamma-aminobutyric acid. The self-assembly of these derivatized calixarenes into heterodimers and homodimers has been studied by NMR in polar solvents such as dimethyl sulfoxide and methanol. |
