    Abstract

    Rhodamine-based chemosensors 1 and 2 were synthesized and self-assembled onto glass surfaces for the selective fluorescent sensing of Pb2+. The immobilized chemosensors showed fluorescent responses that were turned-on with Pb2+ in CH3CN, selectively over various metal ions. The Pb2+-selective fluorescent switch of the immobilized chemosensors was also reversible, allowing for repeated use for Pb2+ detection.
