New Tetrathiafulvalene (TTF) Derivatives Linked to Various Acceptors for Advanced Materials

Molecular assemblies resulting from the linking of TTF as an electron p-donor (D or D moiety) to various p-acceptors (A or A moiety) such as [60]fullerene (1) or quinones (2) are very attractive compounds. Depending of their kind of linking, they can be the subject of intramolecular charge transfer, or they are prone to undergo an intramolecular photoinduced electron transfer. Therefore, they are very useful either as nonlinear optic (NLO) chromophores (3), or for the realization of new artificial photosynthetic systems (4) and, as well as molecular dyads (5), they can be interesting as photovoltaic chromophores. Here are presented some preliminary results dealing with the synthesis and physicochemical properties of assemblies in which D belongs to the tetrathiafulvalene (TTF) series and A to the C60 fullerene series or to the benzoquinone series.
