title: Zinc(II)- and copper(I)-mediated large two-photon absorption cross sections in a bis-cinnamaldiminato Schiff base.
abstract: A Schiff base ligand has been synthesized by condensing 1,2-diaminobenzene with 4-(dimethylamino)cinnamaldehyde to give a donor-pi-acceptor-pi-donor system which does not show any two-photon absorption cross section but which does, upon complexation with Zn(II) or Cu(I), exhibit very high two-photon absorption cross sections.
