Graphdiyne (1) is a member of a novel family of interesting and potentially important allotropes of carbon. Reported herein are the synthesis and spectroscopic characterization of model substructures 2-6. The macrocycles were prepared by the intramolecular cyclization of suitable alpha,omega-polyynes. Key to the success of this approach was the development of an in situ protiodesilylation/alkynylation reaction utilizing reactive phenylbutadiyne synthons. This new method has allowed for the preparation of the largest, most complete substructures of the graphdiyne network to date (3-6).
石墨炔（1）是一类有趣且可能具有重要意义的新型碳同素异形体家族的成员。本文报道了模型子结构2 - 6的合成及光谱表征。这些大环化合物是通过合适的α,ω - 多炔的分子内环化反应制备的。该方法成功的关键在于利用反应性苯基丁二炔合成子开发了一种原位去硅基化/炔基化反应。这种新方法使得制备出了迄今为止石墨炔网络中最大、最完整的子结构（3 - 6）。
