Abstract

Recently, highly third-order nonlinear optical materials with a femtosecond response (τ_R) and no absorption (α) have come to be desired for the development of the ultrafast optical-controlled devices. One of the materials satisfying these optical properties is anticipated to be the organic compound having the nonlinearity caused by the intramolecular charge transfer (ICT) in the nonresonant region.
