Abstract :
The molecular recognition properties of a novel calix[4]arene receptor fixed in a 1,3-alternate conformation bearing two dipyridyl moieties towards organic molecules containing hydroxylic (phenolic oralcoholic) or amino functionalities have been investigated by 1H NMR spectroscopy in CDCl3. The novel receptor selectively recognizes by hydrogen bonding only molecules having two OH phenolic groups.
