Résumé

Push–pull chromophores are widely used and investigated due to their intrinsic electro-optical and non- linear optical properties that are suitable for a variety of applications. However, the grafting and the control of self-organization of such derivatives onto surfaces have been less considered although this may enhance the pre-cited properties and/or enlarge the scope of their use. In this work we present the stepwise synthesis of a novel non-charged push–pull chromophore modified with a fleeting thioacetate group, and the study of its self-assembling abilities onto a gold surface. Self-assembled dense monolayer formation is clearly demonstrated by electrochemical, XPS and STM measurements. Besides, associated with good film quality a conducting behavior consistent with the structure of the SAM-organized push–pull is also highlighted.
