Compounds incorporating the tetrathiafulvalene (TTF) donor unit and one or two cyanoethynylethene (CEE) acceptor units were prepared by Knoevenagel condensations of highly unstable, TTF-linked propargylic aldehyde or ketone derivatives. The resulting TTF-CEEs are very strong chromophores with low-energy end-absorptions beyond 900 nm. The molecules experience reversible oxidations of the TTF unit, and the optical properties of the oxidised species were elucidated by spectroelectrochemistry.
通过高度不稳定的、与四硫富瓦烯（TTF）相连的炔丙基醛或酮衍生物的克诺文纳格尔缩合反应，制备了包含四硫富瓦烯（TTF）供体单元和一个或两个氰基乙炔乙烯（CEE）受体单元的化合物。所得的TTF-CEE是非常强的发色团，在900nm以上具有低能量末端吸收。这些分子经历TTF单元的可逆氧化反应，并且通过光谱电化学方法阐明了氧化态物质的光学性质。
