A new pyrene based chalcone receptor 1 has been synthesized and utilized as a sensor for Pb2+ ions in aqueous media. Receptor 1 showed a highly selective and sensitive recognition of Pb2+ over other heavy and transition metal ions. The turn “off-on” fluorescent detection of Pb2+ by 1 is free from the interference of other metal ions. A possible PET mechanism is proposed for the “off-on” fluorescent enhancement.
