在这里，我们描述了由混合价四硫富瓦烯（TTF）纳米纤维组成的导电流延膜的简易制备。自组装的混合价TTF与有机酸阴离子的纳米纤维生长在薄膜沉积过程中，所得薄膜的电导率显着改变的阴离子的类型。特别地，含有七氟丁酸酯、丙磺酸酯和十一烷磺酸酯的流延膜用作半导体（10（-2）S/cm）。结果表明，阴离子物种在纳米纤维的形成中起着至关重要的作用，并且膜的形态是多样的。
We describe here the facile preparation of conductive casting films consisting of mixed-valence tetrathiafulvalene (TTF) nanofibers. Self-assembled nanofibers of mixed-valence TTF with organic acid anions were grown during film deposition, and the conductivities of the resulting films were significantly altered by the type of the anion. In particular, the casting films containing heptafluorobutyrate, propanesulfonate, and undecanesulfonate work as semiconductors (10(-2) S/cm). It was revealed that anion species played a crucial role in the formation of the nanofibers and the morphology of the film was varied.
