A new smectic type mesophase without in-plane order is presented which is formed by nitro substituted banana-shaped compounds. The structure of this phase is not yet known in detail. The growth of germs and also the textures point to a helicoidal str

We present the structural study of a biforked compound exhibiting a Colr-Colh phase transition. This study was performed by means of DSC, optical microscopy, X-ray diffraction, dilatometry and molecular modelling. The molecular packing within the two

Phase diagrams of different substituted acids with 1-heptyl-4-(4-pyridyl)pyridinium bromide were investigated. The formation of ionic hydrogen-bonded 1 :1 and 1:2 associates can be detected in the solid state. In some cases thermodynamically stable s

New tail-to-tail twins with alkyl or perfluorinated spacers were synthesized. The mesomorphic properties were studied by polarizing microscopy and X-ray diffraction measurements. It was found that the smectic C phase is a S C2 phase with alternating

Various members of two series of μ-halogeno-bridged tetrapalladium mesogens each with twelve dodecyloxy chains, but differing in the size of their large disc-like macroheterocyclic cores, 1 a-e and 2a-c, as well as one new short-chained homologue (1

The game of molecular engineering of liquid crystalline systems via a combination of molecular architecture and functionalization of mesogens has opened interesting perspectives in the field of liquid crystals. Here we report on the synthesis and cha

Examples of specific intermolecular interaction (dipole, EDA, steric interactions as well as hydrogen bonds) are discussed in binary mixtures of calamitic, columnar and polymeric systems. It is shown, that on the base of the complete miscibility in t

To investigate the non-linear optical properties of nitrophenylhydrazones, a series of 4-nitro- and 2,4-dinitrophenylhydrazones of substituted aromatic aldehydes were synthesized. It was found that many of the dinitrophenythydrazone derivatives are l
