A novel 2D carbon allotrope-Graphtetrayne (GTY), features four acetylene linkages between the pairs of benzene rings to form 30-C hexagons was synthesized by a facile synthesized route of Sonagashira cross-coupling reaction of hexaethynylbenzene and diiodobutadiyne. This all-carbon material shows a distinct structural feature, rich triple bonds and super large cavities structures, which not only has high chemical activity, but also show the high stability. GTY displays excellent semiconductor property of conductivity of 3 × 10^–4 S/m at room temperature. GTY films were controlled grown on surface of copper with large areas and controlled thickness, as an efficient Li storage material for the fabrication of high-performance Li-ion batteries. The measured maximum Li storage capacity of GTY reached as high as 947 mA h/g, this is due to high chemical activity and super large porous for high efficient ion transport.

一种新颖的二维碳同素异形体-石墨烯（GTY），其特征在于通过一对乙炔基苯和二碘丁二炔的Sonagashira交叉偶联反应的简便合成途径，在苯环对之间形成四个乙炔键，形成30-C六边形。这种全碳材料具有独特的结构特征，丰富的三键和超大的空腔结构，不仅具有很高的化学活性，而且还具有很高的稳定性。GTY显示出3×10 ^–4的优异的半导体导电性能 室温下为S / m。GTY膜被控制在具有大面积和受控厚度的铜表面上生长，作为制造高性能锂离子电池的有效锂存储材料。测得的GTY最大Li储存容量高达947 mA h / g，这归因于高化学活性和超大多孔性，可实现高效的离子传输。
