Since the first laboratory synthesis of C 60 in 1985, fullerene-related species have been proposed to interpret various astronomical features. After more than 25 years’ efforts, several circumstellar and interstellar features have been convincingly assigned to C 60 , C 70 , and C 60 + $_{60}^{+}$ . These successes resulted from the recent advancements in observational, experimental, as well as computational techniques, and re-stimulated interest in searching for fullerene derivatives in space. As one of the most important fullerene derivatives, hydrogenated fullerene (fullerane) is likely to exist in circumstellar and interstellar conditions. This review gives an overview of the chemical properties and spectral signals of fulleranes focusing on those relevant to astronomy. We summarize previous proposals of fulleranes as the carrier of astronomical features at UV, optical, infrared, and radio wavelengths, and discuss the arguments favoring or disfavoring the presence of fulleranes in astronomical environments. Although no unambiguous detection of fulleranes in space has yet been reported, there are plausible evidences for supporting the formation of certain fullerane isomers.

空间氢化富勒烯（fulleranes）

自 1985 年首次实验室合成 C 60 以来，已提出富勒烯相关物种来解释各种天文特征。经过 25 年多的努力，一些星际和星际特征已令人信服地分配给 C 60 、C 70 和 C 60 + $_{60}^{+}$ 。这些成功源于观测、实验和计算技术的最新进展，以及重新激发了在太空中寻找富勒烯衍生物的兴趣。作为最重要的富勒烯衍生物之一，氢化富勒烯（fullerane）很可能存在于星际和星际条件中。这篇综述概述了富勒烷的化学性质和光谱信号，重点是与天文学相关的那些。我们总结了以前关于富勒烯作为紫外、光学、红外和无线电波长的天文特征载体的提议，并讨论了在天文环境中支持或不支持富勒烯存在的论点。尽管尚未报道在太空中明确检测到富勒烷，但有合理的证据支持某些富勒烷异构体的形成。
