Patent

CA 2505881

A nonlinear optical chromophore having the formula D-.pi.-A, wherein .pi. is a .pi. bridge including a thiophene ring having oxygen atoms bonded directly to the 3 and 4 positions of the thiophene ring, D is a donor, and A is an acceptor, and compositions that include a linear polymer and the chromophore as a pendant group.

L'invention concerne un chromophore optique non linéaire de formule D-.pi.-A, dans laquelle .pi. représente un pont .pi. comprenant un cycle thiophène présentant des atomes d'oxygène liés directement aux positions 3 et 4 du cycle thiophène, D représente un donneur et A représente un accepteur, et des compositions qui comprennent un polymère linéaire et le chromophore en tant que groupe pendant.
