NON-LINEAR OPTICALLY ACTIVE MOLECULES, THEIR SYNTHESIS, AND USE

摘要

In one aspect, the present invention provides a hyperpolarizable organic chromophore. The chromophore is a nonlinear optically active compound that includes a pi-donor conjugated to a pi-acceptor through a pi-electron conjugated bridge. In other aspects of the invention, donor structures and acceptor structures are provided. In another aspect of the invention, a chromophore-containing polymer is provided. In one embodiment, the chromophore is physically incorporated into the polymer to provide a composite. In another embodiment, the chromophore is covalently bonded to the polymer, either as a side chain polymer or through crosslinking into the polymer. In other aspects, the present invention also provides a method for making the chromophore, a method for making the chromophore-containing polymer, and methods for using the chromophore and chromophore-containing polymer.
