Abstract
New macrocyclic ditopic anthracenyl receptors display large chelation-enhanced fluorescence (CHEF) effects upon the addition of linear dications +NH3(CH2)nNH 3+. The amplitude of the effect, which is dependent on the chain length, was at a maximum for propylenediammonium cation. This 1,8-bisazacrown anthracene displays different binding affinities toward metal ions compared to those of 9-azacrown anthracene.
