tetrahedral compounds T1 and T2 that bear four tetrathiafulvalene (TTF) units, which are connected to a tetraphenylmethane core by the ethynylene or amide linker were designed and prepared. Upon one-electron oxidation of the TTF units by Fe(ClO4)3, the resulting TTF+ radical cations stacked intermolecularly to give rise to three-dimensional supramolecular polymers, which were supported by UV–vis spectroscopy
设计并制备了带有四个四硫富瓦烯(TTF)单元的刚性四面体化合物T1和T2,它们通过亚乙炔基或酰胺连接基连接到四苯基甲烷核上。通过Fe(ClO 4)3对TTF单元进行单电子氧化后,所得的TTF +自由基阳离子分子间堆叠,形成了三维超分子聚合物,并通过紫外可见光谱,循环伏安法,动态光散射进行了支持。 ,和扫描电子显微镜。
