A2B2-type push-pull porphyrins as reverse saturable and saturable absorbers

open access: yes, 2007
A2B2-type push?pull porphyrins 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 ...
