DOI: 10.1002/marc.202200761
Abstract: Two liquid crystalline polymers containing an azobenzene or cyanobiphenyl mesogenic side chain that adopt smectic A phases were mechanically mixed at 1:1 mesogen molar ratio at an isotropic phase temperature and then cooled. The resultant… read more here.

DOI: 10.1021/acs.macromol.8b02462
Abstract: Small-angle X-ray scattering and atomic force microscopy were used to observe smectic–smectic phase segregation in binary mixtures of rigid-rod-like helical poly[n-decyl-(S)-2-methylbutylsilane] (PDMS) polymers with molecular-weight ratios of 4.82 and narrow molecular-weight distributions. Phase segregation is… read more here.

DOI: 10.1073/pnas.2217150120
Abstract: We have structurally characterized the liquid crystal (LC) phase that can appear as an intermediate state when a dielectric nematic, having polar disorder of its molecular dipoles, transitions to the almost perfectly polar-ordered ferroelectric nematic.… read more here.
