Data underlying the publication: Confinement-Driven Structural Transitions of Cholesteric Liquid Crystals with Lipid-Decorated Interfaces

Samples. Cholesteric films of 4-cyano-4'-pentylbiphenyl (5CB) doped with 2.8 wt% (S)-4-cyano-4'-(2-methylbutyl)biphenyl (CB15), confined in square polydimethylsiloxane (PDMS) microwells prepared by soft lithography, in contact with aqueous vesicle suspensions of 1,2-dilauroyl-sn-glycero-3-phosphocholine (DLPC), 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) or their mixtures at a total lipid concentration of 10 uM.

Contents. Confocal fluorescence z-stacks (Leica TCS SP8) of the cholesteric-aqueous interface in the microwells, covering 25 conditions: five lipid compositions (DLPC, DOPC, and DLPC:DOPC 1:0.43, 1:1, 1:2.3) at a microwell width of 150 um and depths of 19.6 and 55 um, and at a depth of 55 um and widths of 200, 400 and 500 um. Fast Fourier transform power spectra computed from these micrographs in Fiji/ImageJ, with the radially averaged intensity profiles extracted from them.
