Paper Abstract

Theoretical calculations have demonstrated that the ratio of second and third degree order parameters can define lattice dimensionality and furthermore, that an increased ratio of second to third degree order parameters represents reduced lattice dimensionality. As a result, the third degree order parameter (i.e. acentric order parameter) is increased, causing an increase in electro-optic activity with reduced lattice dimensionality. Experimentally, specific spatially-anisotropic interactions associated with coumarin moieties and Frechet-type (arene/perfluoroarene) dendrons have been incorporated into chromophore systems and have been shown to lead to lattices of reduced dimensionality, resulting in increased values of the acentric order parameter and therefore, electro-optic activity. Reductions in lattice dimensionality can also arise from guest chromophore-host chromophore interactions in binary chromophore organic glasses and from laserinduced ordering of host lattice chromophores observed in the laser-assisted electric field poling of azo-dye-containing host lattices. These interactions in various chromophore systems including investigation of EO and order properties are discussed.
