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. It exhibits strong ultraviolet (UV) PL at 397 nm and optical absorption at ca. 280 nm. It is proposed that the oxygen-containing functional groups in the graphdiyne induce charge transfer, leading to the PL properties. As a new kind of artificially synthesized carbon allotrope, graphdiyne with UV PL have many applications.

Graphdiyne通过交叉偶联反应制备，并通过SEM，TEM，XRD，拉曼光谱和XPS表征。研究了其光致发光（PL）特性。已经发现，石墨二炔的厚度为约3μm。1μm，O / C原子比约为。0.1741和许多含氧官能团。它在397 nm处表现出很强的紫外线（UV）PL，在大约32.9 nm时具有光吸收。280纳米 提出石墨二炔中的含氧官能团诱导电荷转移，从而导致PL性质。具有UV PL的石墨二炔作为一种新型的人工合成碳同素异形体，具有许多应用。
