摘要：
A simple fluorescent chemosensor 1 exhibits a 40-fold fluorescence enhancement upon addition of lead ion and yet is insensitive to most of univalent and divalent metal ions. The high affinity of 1 toward Pb2+ presumably results from the cooperative binding behaviors of two potential metal binding sites: the dicarbonyl and the 15-monoazacrown-5 ether.
