NON-RESONANT TWO-PHOTON ABSORBING COMPOUND, NON- RESONANT TWO-PHOTON EMISSION COMPOUND AND NON- RESONANT TWO-PHOTON ABSORPTION INDUCING METHOD AND LUMINESCENT METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an organic material absorbing two photons in high efficiency, i.e., a material having high two-photon absorption cross-section and provide an organic material exhibiting two-photon luminescence having high luminescent intensity.;SOLUTION: The compound exhibiting non-resonant two-photon absorption is expressed by general formula (1): X²-(-CR⁴=CR³-)_m-C(=O)-(-CR¹=CR²-)_n- X¹...(1) (X¹ and X² are each independently a substituted or non-substituted aryl or a substituted or non-substituted heterocyclic group; R¹, R², R³ and R⁴ are each independently hydrogen atom or a substituent; two or more groups of R¹, R², R³ and R⁴ may be bonded together to form a ring; plural R¹, R², R³ and R⁴ groups may be the same or different when (n) or (m) is 2; and (n) and (m) are each independently an integer of 1-4).;COPYRIGHT: (C)2003,JPO
