摘要

We demonstrate that newly synthesised 7-acetamido-3-hydroxychromones,as well as their parent 3-hydroxychromone (3HC) analogues,exhibit excited-state intramolecular proton transfer reaction in polar protic media including water,resulting in well-resolved two-band fluorescence.Among all 3HCs reported so far,the new compounds show the highest quantum yields ever reported in water (4-13%),while maintaining the sensitive ratiometric response to solvent polarity.This makes them very promising precursors for the development of two-band fluorescent labels and probes,operating in water and other protic media.
