摘要：
A fluorescent Zn2+ sensor 2-(hydroxymethyl)-4-methyl-6-((quinolinyl-8-imino)methyl)phenol (HMQP) based on the 8-aminoquinoline platform has been synthesized This sensor displays high selectivity, sensitive fluorescence enhancement, strong binding ability, and ratiometric response to Zn2+ in Tris-HCl (50 mM, pH 7 54), THF-H2O (9(.)1, v/v). And an obvious color change between HMQP and Zn2+-MQP(-) can be visually observed by the naked eye. The composition of the complex Zn2+-MQP(-) has been found lobe 1:2 based on the fluorescence/absorption titration and further confirmed by X-ray crystallography.
