稀有气体化合物非共价作用研究进展

Research Progress in Noncovalent Interactions of Noble Gas Compounds

稀有气体化合物的非共价作用研究是最近发展起来的一个新兴领域,是非共价领域的重要拓展和延伸。到目前为止,本领域已经取得了一些研究成果。本文着重论述σ-hole、π-hole和稀有气体-π等3类非共价作用。这些新型非共价作用的提出,不但能够帮助研究人员更好地理解稀有气体化合物的各种非共价行为,如结晶、吸湿性等,而且为寻找有效调控其氧化性、爆炸性等性质的方法指明了方向。

Studies on noncovalent interactions of noble gas compounds have emerged just recently, which is an important development and extension of noncovalent interaction realm. Some significant results have been achieved so far in this field, such as the appearance of several new concepts: σ-hole, π-hole and aerogen-π interaction types, which were reviewed extensively herein. Studies on these newly proposed noncovalent interactions not only help researchers to get deeper insights into the noncovalent properties of noble gas compounds, such as crystallization, hygroscopicity, etc., but also provide effective ways of regulating these oxidation and denotation abilities, etc.
