FIG. 1.

(Color online) (a) PL spectra of 2 in acetonitrile and water/acetonitrile mixtures . (b) Plots of fluorescence quantum yields of 1 and 2 vs compositions of the water/acetonitrile mixtures. Inset: photos of the solutions of 2 in the water/acetonitrile mixtures with 0% and 90% water fractions.

FIG. 3.

(Color online) Photos of the spots of dye 2 on the TLC plates placed in the Petri-dish sets (a) without and (b) with saturated chloroform vapors. Photo in panel (c) was taken after the organic vapors in panel (b) had been evacuated.
