Abstract

Organic materials with conjugated 2-D π- election delocalization have shown promise as potential optical computing elements,¹ The dispersive bistability due to saturation absorption at the peak of the absorption spectrum has been observed in polymer SINC² Recently, these materials, especially metallorganies, have been found to show reverse saturable absorption (RSA) at the valley of the linear absorption spectrum. We now report mirroriess transient optical bistability due to RSA observed in copper phthalocyanine (CuPc) solution at nonresonance, we believe for the first time.
