The first blue phase reactive monomers containing a bi-mesogenic core and their side-chain polymers

Two novel blue phase (BP) reactive monomers M1 and M2 containing a bi-mesogenic core are first reported by introducing two end-attached acrylic spacers with different lengths. Due to the self-assembly of bi-mesogenic cores with the same side-by-side end-attached acrylate spacers in homopolymers P1 and P2, no blue phase could be induced by homopolymerization of M1 and M2. However, by interrupting the self-assembly of bi-mesogenic cores with different side-by-side spacer lengths of copolymers P12, double-twisted cylinders of BPIII could be further extended by copolymerization of M1 and M2 with different molar ratios. With M1:M2 = 5:5 (molar ratio) in both side-chain copolymers P12(soln:5/5) and P12(photo:5/5) rather than binary mixture M1/M2(5/5), the widest BPIII ranges of 5.3 °C and 3.8 °C could be obtained by solution- and photo-polymerization, respectively.

Photo-isomerizable derivatives of phenylethanediol and cinnamic acid: Useful compounds for single-layer R, G, and B cholesteric color filters

This article describes the synthesis of derivatives of (R)-phenylethanediol and cinnamic acid. These molecules are photo-isomerizable and contain two acrylate groups that can form densely cross-linked cholesteric polymer films. The Z-isomers formed by irradiation of the E-isomeric cinnamic acid derivatives exhibit a much lower helical twisting power than that of the E-isomers. In this way, the reflection wavelength of cholesteric layers made with these molecules can be increased by irradiation. After polymerization, the cholesteric films are thermally stable and hence these molecules are suitable for use in cholesteric color filters that find application in liquid-crystalline displays.
