Figure 1. Disclination lines and amphiphiles.

Figure 1

a,b, Bright field optical micrograph (a) and schematic illustration (b) of a singular line defect (disclination) of strength −1/2 formed around OTS-treated silica microparticles dispersed in a nematic LC with a 90° twist. Scale bar corresponds to 50 μm. Inset in (b) illustrates local ordering (solid line) of mesogens near the core of the −1/2 disclination (dashed circle). c,d, Molecular structures of BODIPY-amphiphiles (c) and phospholipids (PC-Cn, in which n represents the number of methylene units in each aliphatic tail) (d) used in this study. PC: phosphatidylcholine; PA: phosphatidic acid; PE: phosphatidylethanolamine; PG: phosphatidylglycerol; PS: phosphatidylserine.
