a PL spectra of P4 in THF and THF/water mixtures with different water fractions (fw). Concentration: 10−5 M; excitation wavelength: 313 nm. b The PL intensity enhanced gradually with the water fraction in THF/water mixtures increased, which was visibly showed in the inset. c P4 was filled into the spiral groove of waveguide by spin-coating, and the spiral route of waveguide was taken by microscope with a scale bar of 80 μm. d By taking advantage of AIE, the uniformity and continuity of the spiral waveguide could be visualized by naked eyes upon irradiation by a 445 nm pump light.
