IPC: G02F1/355
Filed: 1987-04-27
Abstract: PURPOSE:To obtain an optical nonlinear response with high speed and high efficiency by using a specified org. nonlinear optical material having large third order nonlinear optical effect. CONSTITUTION:The titled material is shown by the formula DPAI-G1identicalC-G2-NO2 (wherein G1 and G2 are each a group contg. an aromatic or a heterocyclic ring, DPAI is an electron donative substituent group having a pi electron in the substituent group). The main characteristics of said material lies in a point of having the large three dimensional nonlinear optical effect. Namely, the ordinary technical defect of shifting the absorption to the long wavelength side caused by the broadening of the pi-conjugation and increase in the electric charge transfer is solved by realizing a molecular structure which gives rise to the giving the pi electron by the doner only in the excited states. In this way, the nonlinear response with high speed and high efficiency can be obtd.
