Abstract
A novel composition is a solution in an organic solvent of an electron donor-acceptor complex of a conjugated aromatic polyazomethine compound and a Lewis acid compound. This composition is coated on a transparent support and the solvent is evaporated to produce an optical device. Decomposition of the polyazomethine-Lewis acid complex coated on the substrate produces a new optical device comprising a film of the polyazomethine compound on the substrate. Compositions of the present invention can also be used for the preparation of optical wave guides, optical switching elements, fibers, and dielectric materials.
