Fluorescent spectral changes of boronic acid D-1 upon addition of different diols in phosphate buffer (0.1 M) at pH 7.4: λex = 280 nm, λem = 334 nm. (A) D-fructose; (B) D-glucose; (C) D-sorbitol; (D) plots of fluorescent intensity changes of D-1 as a function of sugar concentration: D-fructose (◆), D-glucose (■), D-sorbitol (▲). [D-1] = 5 × 10−6 M.
