Figure 4: Three-phase coexistence in a D1p/D2TTp/PEG mixture.
From: Abiotic ligation of DNA oligomers templated by their liquid crystal ordering
Optical microscopy images of 20-μm-thick flat cell containing a D1p/D2TTp/PEG mixture with [D1p]/[D2TTp]≈1 and cPEG=300 g l−1. The same cell is imaged through crossed (a) and parallel (b) polarizers. Coloured COL domains are visible in a. The internal alignment of the COL domains is nearly uniform, the colours depending mainly on the domain thickness. (b) The coexistence of three phases are as follows: the DNA COL domains, the DNA ISO phase (black in a and pale yellow in b) and the PEG-rich ISO phase background (details in Supplementary Note 7).
