Photoluminescence spectra. a P-1 and b P-2 in THF/water mixtures with different water fractions (fw). Concentration: 10−5 M. λex = 355 nm. c Plots of αAIE versus fw, where αAIE = I/I0 and I0 = maximum emission intensity at fw = 0%. Inset: photographs of P-1 in THF/water mixtures with different fw taken under UV illumination. d Plots of λem–(λem)0 versus different fw. λem: emission maximum of each plot, (λem)0: maximum emission wavelength at fw = 0%
