High-molecular nonlinear optics material

摘要

PURPOSE:To provide high molecular non-linear optical material that excels in formability, workability and also excels in dimensional stability, and suitable for manufacture of an non-linear optical element. CONSTITUTION:It constitutes a characteristic feature that this material is made by containing a chemical compound having a structural unit represented by the formula as a structural component. In the formula R1, R2 represent one kind out of a hydrogen atom, a normal chain whose number of carbon is 1-6 or an alkyl group in a branched shape, a normal chain whose number of carbon is 1-6 or an alkoxy group, a hydroxy group, and a nitro group in a branched shape, or a halogen atom, X represents a substituent group including an electron donative hetero atom such as second-grade or third-grade amino groups, and an oxygen atom, etc., or a hetero atom, Y represents an electron absorptive substituent group such as a nitro group, a cyano group, an ester group, etc., Z represents an oxygen atom or a sulfur atom, and (d) represents one of 0, 1 and 2.
