Fig. 6 Schematic illustration
of a helical pitch gradient of
NÃ-LC film during the
photopolymerization of RM
within the N-LC medium,
chiral dopant and dye, and
their corresponding reflection
light variation in the visible
wavelength region
Fig. 7 Simple molecular stacking patterns of chromonic system exhibiting LLC phase. The LLC
phase is stabilized by the photopolymerization with RM in a dye solution (a). Chemical structure of
perylene-based RM dye (PRMD) complex in the acrylic acid solution (b). Highly oriented film
obtained from shear coating of 25 wt% of PRMD solution and subsequent drying and UV curing
processes (c) and its polarized optical properties (d). Redrawn and replotted from Bae et al. 2011,
