The synthesis, characterization and electrochemical behaviour of novel monomers for use in sol-gel processes are described. These new compounds include a rigid tetrathiafulvalene (TTF) core substituted by one or two spacers, to which a triethoxysilyl group is covalently bonded. The synthesis is based on the preparation of various cyanoethyl-protected TTF thiolates, deprotection and alkylation of thiolate
描述了用于溶胶-凝胶过程的新型单体的合成、表征和电化学行为。这些新化合物包括被一个或两个间隔基取代的刚性四硫富瓦烯 (TTF) 核,三乙氧基甲硅烷基与该核共价键合。该合成基于各种氰乙基保护的 TTF 硫醇盐的制备,硫醇盐与 2-溴乙醇的脱保护和烷基化,以及醇官能团与 3-(三乙氧基甲硅烷基)丙基异氰酸酯的后续缩合。已通过电化学研究研究了标题化合物的供体能力。这些新前体的水解缩聚反应是在 THF 溶液中在亲核试剂(四丁基氟化铵,TBAF)或酸(HCl)催化剂存在下进行的。所得混合固体高度缩聚,并在纳米(X 射线衍射)和微米(双折射)尺度上呈现组织。(© Wiley-VCH Verlag GmbH & Co.
