Spontaneous periodic deformations in nonchiral planar-aligned bimesogens with a nematic-nematic transition and a negative elastic constant (2010)
Journal Article
Panov, V. P., Nagaraj, M., Vij, J. K., Panarin, Y. P., Kohlmeier, A., Tamba, M. G., …Mehl, G. H. (2010). Spontaneous periodic deformations in nonchiral planar-aligned bimesogens with a nematic-nematic transition and a negative elastic constant. Physical review letters, 105(16), Article ARTN 167801. https://doi.org/10.1103/PhysRevLett.105.167801

Hydrocarbon linked mesogenic dimers are found to exhibit an additional nematic phase below the conventional uniaxial nematic phase as confirmed by x-ray diffraction. The phase produces unusual periodic stripe domains in planar cells. The stripes are...

The coexistence of 18 isomers, identified by NMR spectroscopy and gathered into six states with very different absorption properties, is observed upon irradiation with selective wavelengths of a triphotochromic system joining two naphthopyran entitie...
