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 TTF 连接丙炔醛或酮衍生物的 Knoevenagel 缩合反应,制备出了包含四噻富戊二烯(TTF)供体单元和一个或两个氰基乙炔勒烯(CEE)受体单元的化合物。由此制备的 TTF-CEE 是一种非常强的发色团,具有超过 900 纳米的低能末端吸收。这些分子经历了 TTF 单元的可逆氧化,并通过光谱电化学阐明了氧化物的光学特性。
