Photo-release of Zn2+ with fluorescence monitoring has been described using 8-(2,3-dihydrobenzothiazol-2-y1)-7-hydroxy-4-methyl-2H-chromen-2-one (1) as ligand. It is found that I binds to Zn2+ to yield a 1:1 complex (2) with a large binding constant (log K=13.35), 2 exhibits photo-active and occurs photo-release in aqueous micelle solution. Upon irradiation with 365 nm light, 2 undergoes efficient (phi = 0.56) Zn2+-release in buffer solution (PBS, pH = 7.2) to give 8-(benzothiazol-2-yl)-7-hydroxy-4methyl-2H-chromen-2-one (3) as photo-product. 3 exhibits turn-on fluorescence, which is beneficial for monitoring the photo-release.
