We report on the synthesis of new organometallic donor-acceptor molecules for second-order nonlinear optics. They contain ferrocene as the donor group, cyano or tricyano-derivatized furan as the acceptor, and thiophene or 3,3′-bipyridine derivatives as π-bridge. These chromophores can be functionalized, in order to incorporate them later in polymers, covalently or not. To cite this article: A.-L. Roy et al., C. R. Chimie 8 (2005) .

Nous présentons la synthèse de nouveaux chromophores à transfert de charge unidimensionnel (push -pull ) possédant un groupement donneur d'électrons de type organométallique (ferrocène). Ces chromophores sont fonctionnalisés ou non, afin de les incorporer à terme, de façon covalente ou non, au sein de polymères. Pour citer cet article: A.-L. Roy et al., C. R. Chimie 8 (2005) .
