Ye et al. 2004). Some MJLCPs form more ordered columnar phases such as
two-dimensional (2D) hexagonal columnar (Col h ) (Chen et al. 2006b; Tu et al.
2000; Xu et al. 2009) and rectangular columnar (Col r ) (Chen et al. 2006b) phases.
Polymer 4 (Chart 1) with a non-mesogenic bulky side group was first determined by
wide-angle X-ray diffraction (WAXD) to exhibit a Col h structure (Tu et al. 2000).
