Abstract
Two novel photochromic compounds were designed and synthesized; the two-pho ton absorption (TPA) cross section of both were measured with a nanosecond laser pulse; their TPACS (delta) values are around 25 x 10(-46) cm(4) S pho ton(-1) molecule(-1) in acetonitrile; the molecular structure of the target compounds have a 3-methyl-1-benzothiophen-2-yl moiety, which can greatly e nhance the two-photon absorption cross section.
