✦ Synopsis

Novel zinc(II)phthalocyanine having a maclocyclic ether void was synthesized. The phthalocyanine interacted with a paraquat molecule at the crown ether void, resulting in the formation of a molecular complex. The fluorescence quenching of the complex was dramatically enhanced because of the intermolecular folding of the paraquat within the crown ether void.
