Controllable Synthesis of Graphdiyne Nanoribbons

Abstract

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.

Two-Dimensional Carbon Graphdiyne: Advances in Fundamental and Application Research

“…In addition to the 2D film morphology, Chi and co-workers reported the synthesis of well-aligned nitrogen-doped GDYNW on gold surfaces with selective on-surface acetylenic homocoupling reactions (Figure a–d) . Li and co-workers presented the synthesis of GDY nanoribbons with uniform width (4.16 nm in width; Figure e–g) through stepwise inter- and intramolecular Glaser–Hay coupling reaction of ethynyl groups . Liu and co-workers proposed a facile strategy to the controllable synthesis of GDY quantum dots in which pyrene groups are covalently linked to GDY (GDY-Py QDs, 3 nm; Figure h–k) .…”

Detachable all-carbon-linked 3D covalent organic framework films for semiconductor/COF heterojunctions by continuous flow synthesis

“…Raman microscopy therefore show the conjugated diacetylenic linkage as a new peak at 2,196 cm À1 (Figure 4B), confirming the formation of the product in the coupling reaction. 28,[42][43][44] The peaks around 1,600 and 1,300 cm À1 belong to the ring stretching and breathing of aromatic moieties. Compared with the SBFyne monomer (Figure 4B), the typical sharp peak at 2,107 cm À1 representing the terminal alkyne group has disappeared, whereas peaks corresponding to aromatic rings remain, illustrating a high conversion of the reaction.…”

Graphdiyne Electrochemistry: Progress and Perspectives

“…[56] Various liquid-liquid interface methods have been employed to synthesize 2D GDY films. [61][62][63]65,[83][84][85] For example, in 2017 a typical bottom-up synthesis approach was proposed for the first time to synthesize 2D GDY materials. [65] In this case, a dichloromethane solution was placed on a water layer at room temperature, where a copper catalyst was contained.…”
