1. A mesomorphic polymer material, whose structure comprises a skeleton, to which sides chaines are attached, the material resulting from the association of two monomers, each of which includes a component of said skeleton and a side chain which is characteristic for said monomer, characterized in that : - the skeleton (3) is a polyacrylate, a polymethacrylate, a polychloroacrylate for polysiloxane ; - the side chaines are formed from a component specific to the monomers (1, 2) and of a spacer (5, 7) allowing its attachment to the skeleton component ; - the spacer is of the type -(CH2 )n -, with 2=<n=<15, or else of the type -(CH2 -CH2 -O)n -, with 1=<n=<5 ; - the component specific to the first monomer (1) is a mesomorphogenic group (4) having a positive dielectric antisotropy ; - the component specific to the second monomer is a group (6) having the following structure : D - (system of delocalized n-electrons) - A, wherein D is an electron donator grouping and A is an electron acceptor grouping, said specific component being linked to the spacer at the side of the D-grouping. |
