PURPOSE:To obtain the novel nonlinear optical material which exhibits a high nonlinear optical effect by using a specific carbonyl amidine deriv. CONSTITUTION:The nonlinear optical material useful for electrooptical devices, second harmonic wave generating devices, piezoelectric devices, light guides, etc., or optical memory light sources, laser printer light sources, optical switches, etc., consists of the compd. expressed by formula I. In formula I, Ar1 to Ar3 may be the same or different and denote a substd. or unsubstd. aryl group or arom. group contg. a substd. or unsubstd. hetero atom. The novel high- performance nonlinear optical material is obtd. in this way. |
