Abstract
N,N'-Bis(1-naphthylmethyl)-4, 10-diaza-12-crown-4, (2) was found to di splay unique photophysical properties in the presence of the guest met al salts. The diazacrown (2) exhibited high Zn2+ enhancement selectivi ty and in the presence of this cation the host fluorescence intensitie s were increased by a factor of 43. The guest cation-induced fluoresce nce recovery of 2 was higher than N,N'-bis(1-naphthylmethyl)-4,13-diaz a-18-crown-6 (1).
