with the components of modern ferroelectric and antiferroelectric liquidcrystalline mixtures, are confirmed by mass spectrometry (electron ionization) analysis and proton/carbon nuclear magnetic resonance. All the reactive mesogens possess the self-assembling, i.e. liquidcrystalline behaviour with high tendency to create smectic phases in a broad temperature range, which was confirmed by a polarizing

The synthesis and mesomorphism characterization of new thermotropic derivatives of cis,trans and trans,trans-4,4′-bicyclohexyl-bis[4-(6-hydroxyhexan-1-oxy)benzoate] are described. This last intermediate produces a liquid crystalline diacrylate, with lower refractive indices than the well-known aromatic analogues, that allows to obtain polymeric network via UV photopolymerization. The acrylate is very
