摘要：

A layered structure comprises in sequence a substrate, and coated on at least a portion of at least one surface of said substrate a first layer comprising a crystalline uniaxially oriented organic compound, and at least one additional layer comprising a crystalline uniaxially oriented organic compound which is epitaxially vapor deposited on said first layer.A method for providing the layered structure of the invention comprises the steps of(a) providing a substrate,(b) depositing and crystallographically uniaxially orienting a first organic (seed) layer onto the substrate,(c) depositing from the vapor phase at least one additional organic layer onto the oriented seed layer to provide a layered structure wherein the at least one additional layer is epitaxial with the seed layer.
