摘要: A new electronic push–pull fluorophore, 4-amino-1,8-dicyanonaphthalene, and its derivatives have been synthesized efficiently. They can be used as photo-induced electron transfer fluorescence switches which exhibit considerable enhancement induced by transition metal ions Cr3+ Fe3+ also respond to pH values very sensitively.
