摘要： The present invention provides an organic nonlinear optical material including a benzylidene-aniline derivative having an electron-donating substituent introduced at the 4-position and an electron-accepting substituent introduced at the 4'-position, by selecting as the conjugated .pi. electronic system a benzylidene-aniline derivative having a large molelcular hyperpolarizability and yet a dipole moment as small as those of benzene derivatives, and introducing a molecular alignment-regulating substituent. The centrosymmetry in the bulk state of the material, for example, in the crystal state, is destroyed and the molecular alignment is regulated to such a bulk structure so that the optical nonlinearity possessed by the molecule is effectively utilized. The material exhibit a large optical nonlinearity never attained by conventional techniques.the intermolecular cohesive force due to the .pi. electron interaction between the molecules in the present invention is larger than that between a benzene derivative. Consequently, the material has, comparatively, a high melting point, a low subliming property, and a low water-absorbing property. In conclusion, a practically invaluable nonlinear optical material having a high durability in the bulk state and an excellent resistance to laser damage is provided.
