Abstract

original image

Nonlinear optics: A hemicyanine-incorporating silicalite-1 film with second-order nonlinear optical properties supported on a glass plate was prepared. For the nonlinear optical properties of this material the number of hemicyanine dye moleclues included in the zeolite channels is important. Defects arising from Si deficiency along the channels prohibit the diffusion of the dyes into the interior of the zeolite film (see picture).
