Abstract

The second harmonic generation (SHG) parameters for metal-containing ferroelectric liquid crystals are reported for the first time. Some of the materials, based on the structure shown in the Figure, exhibit reasonable NLO efficiencies despite the fact that the molecules themselves do not possess well-defined donor–acceptor arrays.
