Title: A novel and resumable Schiff-base fluorescent chemosensor for Zn(II)
Abstract: A new resumable Schiff-base fluorescent probe 7-methoxychromone-3-carbaldehyde-(3′-hydroxy-2′-naphthaleneformyl) hydrazone (L) was designed and synthesized for selective recognition Zn2+. With the titration and the ESI-MS spectra data, we reached the conclusion that the binding ratio between L and Zn2+ was determined to be 1. The sensor showed a strong fluorescence enhancement in ethanol system of Zn2+ (excitation 430 nm and emission 498 nm). And the enhancement may be due to CN isomerization and Photoinduced Electron Transfer (PET).
