Study of 3 in DMF/H₂O mixtures. a) Normalized emission spectra (λ_exc= 435 nm) with different water fractions (0% – 95%). Concentration of 3: C_3,0 = 19.0 µmol.L⁻¹. b) Distribution of hydrodynamic diameters of the formed aggregates of 3 with different water fractions (75% – 95%), measured with DLS. Concentration of 3: C_3,0 = 19.0 µmol.L⁻¹.
