Fig. 3. (A) Fluorescence spectra of TPEOMeCN in H2O–DMSO mixtures with different water fractions; (B) fluorescent intensity of 423 nm and 518 nm respond to the changes of water fractions in H2O–DMSO mixtures. Concentration: 50 μM; λex: 320 nm (5 nm, 5 nm); 293 K. Inset: the photograph of the solutions (fw = 0%, 50% and 90%) under UV light (365 nm).
