ORGANIC NONLINEAR OPTICAL MATERIAL AND ORGANIC NONLINEAR OPTICAL ELEMENT USING THE MATERIAL
Document Type and Number:
Japanese Patent JPH05158092
Kind Code:
A
Abstract:
PURPOSE:To obtain the material enhanced in second harmonic generation(SHG) activity and not having an absorption in the SHG region by incorporating a specified compd. into the material. CONSTITUTION:The subject material consists of a compd. shown by formula I. In formula I, X1 and X2 are the atom or atomic group selected from a group consisting of the groups shown by formula II and can be different from each other. In formula II, R is 1-8C alkyls or aryls, and R can be hydrogen when at least one between X1 and X2 is not a C-R group. Y is an atomic group having a pi electron conjugated system shown by formula III, and A,...D are hydrogen or an org. substituent. The R in formula II is 1-8C alkyls or aryls, and the 1-8C alkyls are the saturated hydrocarbon groups represented by methyl, isobutyl, etc., the saturated hydrocarbon group having a closed ring structure represented by cyclopropyl, etc.
