通过四硫富瓦烯（TTF）与金离子之间的氧化还原反应产生的电荷转移相互作用，将TTF与金离子的一维堆积结构协同自组装，合成了有机-金属杂化纳米线。在室温下，将TTF和HAuCl 4混合在乙腈溶液中，可以很容易地得到紫色沉淀的纳米线。TTF与HAuCl 4的进料摩尔比为4.4。所观察到的纳米线的平均直径和长度分别为90 +/- 36 nm和15 +/- 3 μ m。中性和氧化的TTF沿着一个方向以混合价态排列促进了形成，这通过出现在2000 nm区域的宽吸收和[（TTFCl 0.78）Au-0.12]纳米线的组成来证实。
Organic-metal hybrid nanowires were synthesized by cooperative self-organization of the one-dimensional stacking of tetrathiafulvalene (TTF) via charge-transfer interaction with metallic gold originating from the redox reaction between TTF and gold ions. The nanowires can be easily obtained as purple precipitates just by mixing TTF and HAuCl4 in a CH3CN solution at room temperature. The feed molar ratio of TTF to HAuCl4 was 4.4. The average diameter and length of the observed nanowires were 90 +/- 36 nm and 15 +/- 3 mu m, respectively. The formation was facilitated by the arrangement of the neutral and oxidized TTF along the one direction in a mix-valence state, which was confirmed by a broad absorption that appeared in the region of 2000 nm and the composition of the nanowires of [(TTFCl0.78)Au-0.12].
