(A-D) Preparation of LC droplets of predetermined sizes within polymeric multilayer shells. Polymeric shells were prepared by sequential deposition of PSS and PAH onto silica templates (B) and subsequent etching of the silica (C). The resulting polymeric shells were then filled with LCs (D). (E) Bipolar and (F) homogeneous director configurations. (G, J, L, O) Polarized and (H,K, M, P) bright-field optical micrographs of polymer-encapsulated 5CB droplets with (G,H) diameters of 8.0 ± 0.2 μm and bipolar LC ordering, (J, K) diameters of 1.0 ± 0.2 μm and preradial LC ordering (J and K show the end on views of the preradial ordering whereas L and M show side views), and (O, P) diameters of 0.70 ± 0.08 μm and radial LC ordering. Point defects in the LCs are indicated by white arrows. Cartoons in I, N, and Q show bipolar, preradial, and radial ordering of the LC droplets, respectively. The scale bars are 2 μm for G, H, and J-M and 1 μm for O and P. Reproduced with permission from ref 92 (Wiley-VCH).
