| 英文摘要 | We report two fluorescent Zn(2+) sensors, AD1 and AD2. In aqueous solution, upon addition of Zn(2+). AD1 only showed the enhancement on the fluorescence intensity, while AD2, acting as a ratiometric sensor, demonstrated the variations not only on the fluorescence intensity but also on the emission wavelengths. Both sensors exhibit high sensitivity (nM level) and selectivity for Zn(2+) over Na(+), K(+), Mg(2+), and Ca(2+) at the millimolar level. Moreover, AD2 undergoes significant increase of the TPA cross sections (delta(max)) at 840 nm by the Zn(2+)-coordination induced ICT enhancement. The laser scanning confocal microscopy experiments revealed that AD2 is cell-permeable and can indeed visualize the changes of intracellular Zn(2+) in living cells through a ratiometric approach by utilizing two-photon excitation.
