摘要：
Fluorescent photoinduced electron-transfer sensors were made from p-phenylenediamine-substituted azacrown ethers attached with a dansyl group, in which the p-phenylenediamine moiety serves as electron donor and the dansyl group acts as the acceptor. Chelation-enhanced fluorescence was observed upon addition of metal salts. Selective fluorescence response was observed for Mg2+ and/ or Ca2+ versus Na+ and K+ due to size match and charge density sensitivity of the p-phenylenediamine moiety.
