(57) [Abstract] [Purpose] To provide a third-order nonlinear optical material capable of achieving both large third-order nonlinear susceptibility and high-speed response. [Structure] General formulas (1) to (4): [Wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are as described in the description. ] It consists of the quinone derivative represented by either. |
