Liquid Crystalline Phases

A series of C2-symmetric compounds with different core sizes and varying lengths and numbers of alkoxy side chains were prepared, and the factors influencing their liquid crystalline mesophase behaviour were investigated. The compounds studied were based on benzophenone, dibenzylidene-acetone, and 1,9-diphenyl-nona-1,3,6,8-tetraen-5-one cores with either 1 or 2 linear alkoxy side chains. The side chains were varied in length from C6H13 to C12H25. The liquid crystalline mesophase behaviour of the compounds was investigated using differential scanning calorimetry, polarizing optical microscopy, and small-angle X-ray scattering (SAXS). It was found that a number of the molecules were able to self-assemble into smectic and nematic liquid crystalline phases.

AbstractMesomorphic structures of hydrogen bridged poly(4-vinylphenol) - N,N-dimethyl- n-octadecylamine (PVPh-NDOA) and PVPh - N,N-dioctadecylmethylamine (PVPh-DOMA) mixtures were investigated by means of wide angle X-ray diffraction, small angle X-ray scattering, and IR spectroscopy. Octadecyl chains of the PVPh-NDOA and PVPh-DOMA mixtures showed hexagonal αH and orthorhombic βO packing, respectively. In addition, PVPh-NDOA and PVPh-DOMA formed lamellar structures with periods of 3.5 and 2.5 nm, respectively.
