Abstract
This invention concerns new molecules with active, non-linear optical properties and which can be thermally reticulated (more precisely, these molecules include terminal functions which can be reticulated, attached to either side of the groups active in non-linear optics, which can be oriented under an electrical field). When reticulated and oriented under an electrical field, these materials are particularly stable and can be employed for industrial applications, using non-linear optics (electrooptical modulators, frequency doublers, etc.).
