Improved donor groups for chromophores play a major role in the development of organic materials for nonlinear optics. Guanidyl and phosphoraniminyl residues are examined as donors in one-dimensional organic nonlinear optical chromophores such as that shown in the Figure. The results of electrooptical absorption (EOAM) and electric field induced second harmonic generation (EFISH) measurements are presented and discussed.
