The synthesis of a series of push-pull systems [donor (D)–acceptor (A)], associating the 1,3-dithiol-2-ylidene moiety (D) to various (A) fragments through polyolefinic linkages of various lengths, is described. Design optimization of these NLO phores isvia systematic determination of the molecular first hyperpolarizabilities beta; by the EFISH method. Selected compounds of this series, displaying the highest beta; values, are then chemically functionalized in order to promote their covalent grafting to polymeric backbones.
