Abstract
The 3a, b and c supramolecular complexes of the [CE...H3N+R]BPh4- type (where H3N+R is the cation of L-alanyl-p-nitroanilide, BPh4- is the a nion of tetraphenylborate and CE is a crown ether like 18C6, DCH18C6 o r B18C6) were obtained in high yield, in solid state. The obtained sup ramolecular complexes were optically active and hydrophobic. The exper imental results regarding the complex characteristics (UV, H-1-NMR, C- 13-NMR and alpha(D)) and also their stability in water/methylene chlor ide biphasic system are presented.
