Fig. 1: Schematic illustration of four typical LC phases assembled from DBCs.
From: Liquid-crystalline behavior on dumbbell-shaped colloids and the observation of chiral blue phases
Schematic illustrations of the geometrical parameters of DBCs and the corresponding assembled BP III, N2, N1, and SmA phases. De and Dc are the diameters of the end block and central block, respectively. Le and Lc are the lengths of the end block and central block, respectively. RL is the ratio of lengths of end blocks to central blocks. t1 and t2 are the long axis of the chiral column and the layer normal of the barrel-like chiral twist, respectively. 1/2P is the half helical pitch.
