Preparation of a Large Amount of Ultrathin Graphdiyne

Chemistry – A European Journal, 2022
AbstractWe report a facile strategy to prepare a large amount of ultrathin graphdiyne (GDY) with good crystallinity in the mixture of oil–water systems. By simply mixing the solution of GDY monomer in CHCl3 and the copper acetate solution as a catalyst in water and stirring at room temperature, ultrathin GDY films with a thickness of ∼4 nm were ...

Architecture of graphdiyne nanoscale films

Chemical Communications, 2010
We have demonstrated a methodology to generate large area graphdiyne films with 3.61 cm(2) on the surface of copper via a cross-coupling reaction using hexaethynylbenzene. The device based on graphdiyne films for measurement of electrical property is fabricated and shows conductivity of 2.516 x 10(-4) S m(-1) indicating a semiconductor property.

Intrinsic magnetism of graphdiyne

Applied Physics Letters, 2017
Graphdiyne (GDY) was prepared by a cross-coupling reaction and its magnetic properties were studied. The results show that the as-prepared GDY is spin-half paramagnetism. GDY shows the increase in the spin density by annealing, and antiferromagnetism appears after annealing at 600 °C.

First-principles simulation of X-ray spectra of graphdiyne and graphdiyne oxides at the carbon K-edge

Physical Chemistry Chemical Physics, 2023
The experimental C 1s near-edge X-ray absorption fine-structure (NEXAFS) spectra of graphdiyne (GDY) show an evident change at different exposure periods, which is explained by oxidation.

Fundament and Application of Graphdiyne in Electrochemical Energy

Accounts of Chemical Research, 2020
The artificial synthesis of graphdiyne (GDY) in 2010 successfully fills the blank of low temperature preparation of all-carbon allotropes. GDY is an emerging two-dimensional (2D) planar carbon material composed of benzene rings moieties (sp2 carbon atoms), butadiyne (sp carbon atoms) linkers, and well dispersed electron-rich cavities, forming a large π-

On the Dynamics of Graphdiyne Hydrogenation

MRS Proceedings, 2013
ABSTRACTGraphene is a two-dimensional (2D) hexagonal array of carbon atoms in sp2-hybridized states. Graphene presents unique and exceptional electronic, thermal and mechanical properties. However, in its pristine state graphene is a gapless semiconductor, which poses some limitations to its use in some transistor electronics.

Synthesis and photoluminescence of graphdiyne

New Carbon Materials, 2018
Abstract Graphdiyne was prepared by a cross coupling reaction and characterized by SEM, TEM, XRD, Raman spectroscopy and XPS. Its photoluminescence (PL) properties were investigated. It was found that the graphdiyne has a thickness of ca. 1 μm, a O/C atomic ratio of ca. 0.1741 and many oxygen-containing functional groups.

Research on the Preparation of Graphdiyne and Its Derivatives

Chemistry – A European Journal, 2019
AbstractAs a new 2D carbon material allotrope composed of sp and sp2 carbon atoms, graphdiyne (GDY) possesses a highly conjugated porous structure, easily tunable intrinsic bandgap, and various excellent properties. Such properties allowed researchers to develop methods to prepare GDY, so that it can be applied for energy storage and conversion ...
