The synthesis of different unsymmetrical new alkoxynitrostilbenes bearing one or
two monomers groups, as optimized nonlinear optical (NLO) chromophores, are described
herein. The considered functions were acrylate and triethoxysilyl groups. The goal
is to synthesize molecules with a large quadratic NLO polarizability and relative
high solubility in photopolymerizable media that could also be permanently frozen
by orientation in an electric field and photopolymerization.
