Additions of ethyl or tert-butyl diazoacetates to 4-substituted cyclopentenes 6 and 17 under dirhodium tetraacetate/tetraoctanoate catalysis led to mixtures of tert-butyl endo,exo- and exo,exo-3-carboxyl(aryl)bicyclo[3.1.0]hexane-6-carboxylates 7 and

A series of liquid crystalline 3,4-difluoropyrrole derivatives have been synthesized, and their dielectric anisotropy, birefringence, viscosity and phase sequences have been measured. This novel class of compounds showed extremely large dielectric an

For the calculation of anisotropic properties of nematics the knowledge of the order parameter is necessary. The order parameter is not a universal function for all nematics, but there are substance specific differences. As an approximation, we have

New banana-shaped monomers 1a–1f, based on the 1,3-phenylene bis{4-[4′-(alkenyloxy)benzoyloxy]}benzoate bent structure were prepared. The central 1,3-phenylene ring was either unsubstituted (1a, 1b) or had a 2-methyl substituent (1c, 1d) or a 4-c
