Until now, there has been very little experimental evidence for the existence of free arsinidenes and stibinidenes, apart from the hydrides, AsH and SbH. Here, we report on photogeneration of triplet ethynylarsinidene, HCCAs, and triplet ethynylstibinidene, HCCSb, from ethynylarsine and ethynylstibine, respectively, in solid argon matrices. The products were identified using infrared spectroscopy and the associated UV absorption spectra are interpreted with the aid of theoretical predictions.
到目前为止，除了氢化物AsH和SbH之外，几乎没有关于游离亚胂烯和亚锑烯存在的实验证据。在此，我们报告了在固体氩基质中分别由乙炔基胂和乙炔基锑生成三线态乙炔基亚胂烯（HCCAs）和三线态乙炔基亚锑烯（HCCSb）的光化学过程。通过红外光谱对产物进行了鉴定，并借助理论预测对相关的紫外吸收光谱进行了解释。
