Bisfunctionalized ferrocene NLO-phore monomers were prepared. Several ferrocene NLO-phores were characterized by single-crystal molecular structures. The new ferrocene monomers were successfully polymerized using a Knoevenagel polycondensation technique. The polymers were characterized by spectroscopic and GPC data. A very recent use of ferrocene complexes has appeared in the area of nonlinear optical NLO materials. Based on both theory and experimental data, ferrocene compounds possess large hyperpolarizability values. These data combined with excellent thermal and photochemical stability make ferrocene systems a top organometallic candidate for use in NLO materials. Our research program has recently demonstrated that a ferrocene complex bound to polymethyl methacrylate copolymer can be successfully aligned and exhibit the optical property of second harmonic generation.
