Fluorescence spectra of a LCPC-S/D (blue line for initial state and cyan line for PSS365), b LCPC-D/T (blue line for initial state and yellow line for PSS365), c LCPC-S/T (blue line for initial state and purple line for PSS365), and d LCPC-S/D/T films (blue line for initial state and silver gray line for PSS365) in different states (λex = 365 nm). e Fluorescent images of LCPC films showing the emission color changes under UV irradiation. f LCPC films with full-color emission under UV irradiation by blending different ratios of trichroic LCPCs. g CIE chromaticity diagram of full-color LCPC films in PSS365. h CPL spectra of full-color LCPC films in PSS365 (λex = 365 nm) (blue line for LCPC-S, green line for LCPC-D, red line for LCPC-T, cyan line for LCPC-S/D, yellow line for LCPC-D/T, purple line for LCPC-S/T, and silver gray line for LCPC-S/D/T). Fluorescent images of i a rainbow film fabricated by the bar-coating method, j colored letters fabricated by direct ink writing, and k digital programming facilitated by photomasks (The scale bars are 1 cm).
