Abstract
The invention relates to polymeric materials usable in non linear optics. The structure of the material of the invention includes a skeleton to which side chains are attached, the material resulting from the association of a first and a second monomer, the first monomer including a mesomorphogenic group connected to the skeleton by a spacer, the second monomer including a group capable of generating the second harmonic of an electromagnetic wave and also being connected to the skeleton by a spacer.
