A perylenediimide reactive mesogen (PLD-RM) was newly programmed and synthesized for the development of color-changeable smart polarizers with redox property. The optical and structural results obtained by scattering, spectroscopy, and microscopy experiments indicate that PLD-RM shows a self-assembled lyotropic chromonic liquid crystal (LCLC) phase through π-π stacking and ionic repulsion between PLD-RM clusters. The color-changeable smart polarizer is fabricated using mechanical shear, water solution (PLD-RM:water:acrylic acid = 40:20:40 wt.%) and photopolymerization. The absorption wavelength is a specific wavelength (500 nm) in the neutral state and the entire wavelength of visible light in the dianion state. Smart polarizer made with PLD-RM can apply to color-changeable smart window and anti-counterfeiting filter.
