  The invention provides compounds of formula I: wherein A1 to A4are independently selected from the group consisting hydrogen, a methyl group and a hydrocarbon group containing from 2 to 80 carbon atoms in which one or more carbon atoms are optionally replaced by a heteroatom selected from the group consisting -O-, -S- and -N- with the proviso that firstly no two heteroatoms are joined together and secondly that at least one of A1 to A4 includes a polymerisable group; B1represents a hydrocarbon group containing from 4 to 80 carbon atoms, in which one or more carbon atoms are optionally replaced by a heteroatom selected from the group consisting -O-, -S- and -N- with the proviso that no two heteroatoms are joined together; MG1 and MG2are the same or different and each independently represents an aromatic or non-aromatic carbocyclic or heterocyclic ring system containing from 1 to 80 carbon atoms, with the proviso that firstly at least one of MG1 and MG2 comprises at least two ring systems and secondly, when MG1 and MG2 are identical each of A1 and A2 or A3 and A4 are different. The invention also provides liquid crystalline mixtures and optical or electro-optical devices including compounds of formula (I).

• Effect of molecular parameters on thermomechanical behavior of side-on nematic liquid crystal elastomers

  We investigated the structure-property relationship of liquid crystal elastomers (LCEs) obtained from a series of nematic side-on monomers. A new synthetic strategy was developed to obtain the acrylate monomers (n-ADBB), which gave us the opportunity to easily modify the spacer lengths of the monomers. Through magnetic field alignment, well-defined LCE micropillars were fabricated from the monomers by a method combining soft lithography and photopolymerization/photocrosslinking of the monomers and a crosslinker. The influence of structural parameters on the thermomechanical deformation of the microstructures was studied through microscopic observations. The study quantitatively revealed the correlation of thermomechanical behavior of the microstructured LCEs with the crosslinking density and length of the flexible spacer linking the mesogenic core to the backbone. With a proper control of the structural parameters, optimized performances such as large reversible contraction, good elasticity and mechanical robustness were demonstrated for this type of LCEs.
