Rhodamine-based chemosensing monolayers on glass as a facile fluorescent "turn-on" sensing film for selective detection of Pb2+.
Rhodamine-based chemosensors 1 and 2 were synthesized and self-assembled onto glass surfaces for the selective fluorescent sensing of Pb(2+). The immobilized chemosensors showed fluorescent responses that were turned-on with Pb(2+) in CH(3)CN, selectively over various metal ions. The Pb(2+)-selective fluorescent switch of the immobilized chemosensors was also reversible, allowing for repeated use for Pb(2+) detection.
