摘要：

In a cryptand-based fluorescent signaling system with the configuration '' fluorophore-spacer-receptor '', attachment of the electron-withdrawing 2,4-dinitrobenzene groups to the cryptand receptor renders it highly selective for Cu(II). The system exhibits dual monomer and exciplex emissions in the presence of either of Cu(II) and H+ as input with concomitant movements of one of the 2,4-dinitrobenzene groups.
