The complexing behaviour of 2,2'-bithiazole-containing calix[4]arenes
towards Cu-I was investigated. The extinction of the intrinsic blue fl
uorescence of the free ligands upon addition of stoichiometric amounts
of the metallic salt was used as complexation probe. This extinction
was directly related to the chelation of the metal and allowed the con
trolled synthesis of new mono- and dimetallic complexes which were ful
ly characterized.
