A highly selective and sensitive fluorescent chemosensor for Zn2+
摘要:
A new selective Zn2+ fluorescent chemosensor,o-vanillin-4-ethoxybenzoylhydrazone(1),was designed and prepared.Free 1 mainly displayed very weak fluorescence at 480 nm upone xcitation at 403 nln.It displayed high selectivity for Zn2+ and had a 518-fold fluorescent enhancement upon binding of Zn2+, while the other cation ions had only little influence on the fluorescence of 1.Mechanism of enhancement of 1's fluorescence by Zn2+ was briefly discussed.
