Nonlinear optical chromophore compositions which display lyotropic nematic liquid crystal phases in polar organic solvents and provide a mechanical anisotropic effect allowing for the formation of a non-centrosymmetric chromophore-polymer matrix without the application of an electric field. L'invention concerne des compositions chromophores optiques non linéaires qui présentent des phases de cristaux liquides nématiques lyotropiques dans des solvants organiques polaires et produisent un effet anisotrope mécanique permettant la formation d'une matrice chromophore-polymère non centrosymétrique sans l'application d'un champ électrique.
