Graphdiyne nanoribbons with high chemical precision are of great significance for further understanding of the intrinsic properties of graphdiyne and the relationship between structure and properties. However, the reliable synthesis of graphdiyne nanoribbons with chemical precision remains a significant challenge. A facile method is now presented for fabrication of graphdiyne nanoribbons with uniform width through stepwise inter- and intramolecular Glaser-Hay coupling reaction of ethynyl groups. The synthetic ribbons were interwoven into nanotextiles by π-π stacking and were applied for protective coating of Li-electrode in Li-ion batteries, which efficiently suppressed the growth of the Li dendrites during cycling and prolonged the life span of Li-metal batteries.

Graphdiyne纳米带的可控制合成。

具有较高化学精度的石墨二炔纳米带对于进一步了解石墨二炔的内在性质以及结构与性质之间的关系具有重要意义。然而，以化学精度可靠地合成石墨二炔纳米带仍然是一项重大挑战。现在提出了一种通过乙炔基的逐步的分子间和分子内Glaser-Hay偶联反应制备宽度均匀的石墨二炔纳米带的简便方法。合成带通过π-π堆叠交织到纳米织物中，并用于锂离子电池中锂电极的保护涂层，有效抑制了锂枝晶在循环过程中的生长，并延长了锂金属电池的使用寿命。
