PURPOSE:To attain high-speed responsiveness by incorporating a charge transfer complex which contains an electron-donating component and electron-acceptive component in such a manner that the one component is an org. molecule having a pi electron conjugation system and which is formed in the ground state into the above material. CONSTITUTION:This third-order nonlinear optical material contains the charge transfer complex which contains the electron-donating component and electron- acceptive component selected respectively by one from the following groups in such a manner that at least one component thereof is the org. molecule having the pi electron conjugation system and which is formed in the ground state. (electron-acceptive component): cyano compd., quinones, nitro compd., acid anhydride, halogen, and carbon halide, (electron-donating component): unsatd. cyclic hydrocarbon compd., unsatd. heterocyclic compd., chalcogen containing compd., quaternary ionic unsatd. heterocyclic compd., metals. The element which is exceptionally outstanding in terms of the dependency on wavelengths and the input light intensity necessary for response time action is obtd. in this way. |
