摘要：

A novel ratiometric fluorescent probe 1, consisting of Boranil derivative as the fluorophore and picolinate as the recognition site for Cu2+, was designed and synthesized. 1 was found to display ratiometric response while interacting with Cu2+ by undergoing a Cu2+-promoted hydrolysis of the picolinate moiety for the release of its precursor, 2. We observed that 1 not only showed quick response time (within 10 min), high sensitivity (detection limit of 0.52 mu M), and high selectivity for Cu2+ over other metal ions, but also allowed us to detect Cu2+ in a convenient way of observing fluorescence color change under a 365 nm UV lamp using naked eyes. Our study introduced the first ratiometric fluorescent probe for Cu2+ based on Boranil derivative.
