摘要
Bis(coumarinyl) Schiff base I was designed and synthesized as a fluorescence turn-on chemodosimeter for Fe(3+). The chemodosimeter was readily synthesized in four steps from 2,4-dihydroxybenzaldehyde. The addition of Fe(3+) to chemodosimeter 1 induced about a 140-fold enhancement in fluorescence. Furthermore, chemorlosimeter 1 was also highly selective to Fe(3+) over other metal ions, and most of the related metals ions exhibited negligible detection interference.
