Patent

CA 2565705

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.

Dans un aspect, la présente invention concerne un chromophore organique hyperpolarisable. Ce chromophore est un composé optiquement actif non linéaire comprenant un .pi.-donneur conjugué à un .pi.-accepteur par l'intermédiaire d'un pont à conjugaison des électrons .pi.. Dans d'autres aspects, l'invention concerne des structures de donneur et des structures d'accepteur. Dans un autre aspect, l'invention concerne un chromophore contenant un polymère. Dans un mode de réalisation, le chromophore est incorporé physiquement dans le polymère en vue de l'obtention d'un composite. Dans un autre mode de réalisation, le chromophore est lié par covalence au polymère sous la forme d'un polymère à chaîne latérale ou par réticulation dans le polymère. Dans d'autres aspects, l'invention concerne également un procédé de fabrication d'un chromophore, un procédé de fabrication du polymère contenant un chromophore ainsi que des procédés destinés à utiliser ce chromophore et ce polymère contenant un chromophore.
