<p>A novel organic non-linear optical material and a device using the same are disclosed. The material hardly makes reversal symmetrical molecular configuration in a bulk state such as a crystal and a thin layer and shows a high non-linear optical effect. A non-linear optical device using the material has an excellent properties. The organic non-linear optical material is comprised of the following compound: <CHEM> wherein R1, R3 and R4 are independently a hydrogen atom, a cyano group, a phenyl group, an amino group, an alkoxy group, an acylamino group, an alkylthio group, an alkyl group, an alkoxyycarbonyl group, carbamoyl group or a heterocyclic group, provided that R3 is allowed to link together with R4 to form a ring and R1, R3 and R4 are not hydrogen atom at the same time; R2 is a hydrogen atom, an alkyl group or an acyl group; and said groups represented by R1, R2, R3, R4 and the ring formed by linking the groups represented by R3 and R4 are allowed to have a substituent.</p> |
