The Next Generation of Carbon Allotropes: On the Way to Carbyne and Graphyne (A04)

拟议的研究将通过合理地合成基于SP杂化碳的新的同素异形体，即卡宾和图(二)炔，将自然的多样性扩展到已知的碳同素异形体(例如，富勒烯、纳米管、石墨烯和钻石)之外。对于卡宾，将考察聚炔和累积烯作为模型体系，以探索散装卡宾实际上是两者的混合体的假设。将对合成材料进行技术相关的电子和光学性能评估，特别是它们作为分子线的能力。

The proposed research will extend Nature's diversity beyond the known carbon allotropes (e.g., fullerenes, nanotubes, graphene, and diamond) through a rational synthesis of new allotropes based on sp-hybridized carbon, namely carbyne and graph(di)yne. Toward carbyne, both polyynes and cumulenes will be examined as model systems, in order to explore the hypothesis that bulk carbyne is actually a hybrid of both. Synthesized materials will be evaluated for technologically relevant electronic and optical properties, particularly their ability to serve as molecular wires.
