摘要: 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 degrees C and 3.8 degrees C could be obtained by solution-and photo-polymerization, respectively.
