ORGANIC NONLINEAR OPTICAL COMPOUND AND ORGANIC NONLINEAR OPTICAL MATERIAL CONTAINING THE COMPOUND

摘要

PURPOSE: To obtain, an org. nonlinear optical compd. enhanced in second-order and third-order molecular nonlinear susceptibility and with the monomolecular dispersion concn. in a medium increased by incorporating a specified compd. and a transparent medium into the compd. ;CONSTITUTION: This org. nonlinear optical compd. contains at least one kind of compd. shown by the formula and a medium. In the formula, R¹, R² and R³ are independently hydrogen atom, alkyls or substituted alkyls. The compd. can be dispersed in the medium in high concn., the soln. is very easily prepared without any troublesome means such as crystal growth, and a material having extremely large nonlinearity and an wavelength shifting element are formed by spin coating, etc. Consequently, the compd. is widely used for an optical functional element based on the nonlinear optical effect.;COPYRIGHT: (C)1993,JPO&Japio
