Abstract
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) fra gments through polyolefinic linkages of various lengths, is described. Design optimization of those NLO phores is cia systematic determinati on of the molecular first hyperpolarizabilities beta by the EFISH meth od. Selected compounds of this series, displaying the highest beta val ues, are then chemically functionalized in order to promote their cova lent grafting to polymeric backbones.
