TWO-PHOTON ABSORPTION MATERIAL AND APPLICATION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an organic material with a large two-photon absorption cross-sectional area, a new two-photon absorption optical recording material with which recording and playing back are feasible, and a recording medium.SOLUTION: A two-photon absorption material is composed of a salen metal complex which is formed of a Schiff base formed of an o-phenylenediamine derivative and 4-diethylamino salicylaldehyde or the like and a metal atom selected from Ni, Pd, and Cu.
