摘要

The synthesis and photophysical properties of a fluorescent anthracene-urea derivative,which can associate with anions,such as acetate or phosphate,by hydrogen-bonding,are reported.A new anthracene derivative bearing phenyl-urea group at the 9-position of anthracene,1-anthracen-9-yl-3-phenylurea,(9PUA)was prepared.9PUA was found to exhibit strong selectivity in relation to anions,some of which showed a remarkable change in emission.9PUA had a monomer emission maximum at 450 nm,and the monomer emission was quenched to give a new emission with a maximum at 580 nm on the addition of acetate anion.The emission at 580 nm was assigned to a tautomer form of 9PUA generated by intermolecular proton transfer as a result of an excited-state reaction with acetate anion.
