Abstract

A₂B₂-type push–pullporphyrins with a strong intramolecular dipole moment have been prepared via Heck and Suzuki coupling reactions as novel materials for use in nonlinear optics (NLO); they display saturable (SA) and reverse saturable absorption (RSA) properties at 532 nm and their nonlinear optical response is characterized by RSA occuring at lower intensity levels whereas the onset of SA prevails at higher levels.
