Paper Abstract

Multilayer assembly of organic chromophores with inorganic interlayers is a facile technique for the preparation of nonlinear optical materials with well-defined architectures. Recent reports of T. M. Mallouk (University of Texas-Austin) have indicated that zirconium organodiphosphonates form particularly stable surface multilayers that can be constructed straightforwardly one monolayer at a time. We have synthesized a series of chromophores with shapes and functional groups designed for layerwise deposition as zirconium phosphonates. These include electron donating thiophene oligomers, electron accepting quinodimethanes, and dipolar azo dyes. Cohesive, electrically insulating, thermally stable films of these compounds as layered phosphonates on various substrates were prepared with predictable thicknesses and, in some cases, polar order. Second harmonic intensity from the polar azo dye films was proportional to the thickness squared, consistent with theory. The dielectric and optical responses of a variety of other kinds of samples are discussed.
