摘要：

Several donor-sigma-acceptor compounds (8, 9, 13, and 14) have been synthesized that contain a sterically hindered quinone tethered by a tetramethylene chain to a substituted tetrathiafulvalene. Compounds 13 and 14 show a dramatic increase (approximate to 450 mV) in the oxidation potential of the dipyrrolo-TTF unit, suggestive of considerable electron withdrawal through the sigma-bridge. Monolayers of 9 and 14 are metastable at the air-water interface.
