我们报道了原子尺度的单晶银纳米线的合成。在水相中，通过电化学/光化学氧化还原反应，在自组装杯[4]对苯二酚纳米管的孔内生长出宽度为0.4 nm的极细银线，其长度可达微米级。本发明的亚纳米线在环境空气和水环境下非常稳定，不像之前报道的直径类似于1纳米的金属线，其仅在超高真空中短暂存在。这些线以相干取向的三维阵列的形式存在，因此可以用作研究一维现象的模型系统和设计纳米电子器件的纳米连接器。
We report the synthesis of single-crystalline silver nanowires of atomic dimensions. The uttrathin silver wires with 0.4 nanometer width grow up to micrometer-scale length inside the pores of self-assembled calix[4]hydroquinone nanotubes by etectro-/photochemical redox reaction in an ambient aqueous phase. The present subnanowires are very stable under ambient air and aqueous environments, unlike previously reported metal wires of similar to1 nanometer diameter, which existed only transiently in ultrahigh vacuum. The wires exist as coherently oriented three-dimensional arrays of ultrahigh density and thus could be used as model systems for investigating one-dimensional phenomena and as nanoconnectors for designing nanoelectronic devices.
