Patent ID: 7125578

Claim:
A method for generating materials which exhibit photoinduced charge transfer having a controlled direction, which comprises the steps of: (a) depositing a donor layer directly onto a substrate, the substrate consisting of non-conductive glass, wherein the donor layer comprises at least one of an electron donor and an energy donor; (b) depositing a nonlinear optical chromophore material directly onto the donor layer; (c) depositing an acceptor layer directly onto the nonlinear optical chromophore material, wherein the acceptor layer comprises at least one of an electron acceptor and an energy acceptor; and (d) self-assembling the donor layer, the nonlinear optical chromophore material layer, and the acceptor layer into a superlattice, whereby photoinduced charge transfer is achieved between the donor layer and the acceptor layer, thereby enhancing the nonlinear optical properties of the nonlinear optical chromophore material.
