Two-dimensional materials are responsible for changing research in materials science. After graphene and its counterparts, graphane, fluorographene, and others were introduced, waves of renewed interest in 2D binary compounds occurred, such as in metal oxides, transition-metal dichalcogenides (most often represented by MoS ), metal oxy/hydroxide borides, and MXenes, to name the most prominent. Recently, interest has turned to two-dimensional monoelemental structures, such as monolayer black phosphorus and, very recently, to monolayer arsenic, antimony, and bismuth. Here, a short overview is provided of the area of exponentially increasing research in arsenene, antimonene, and bismuthene, which belong to the fifth main group of elements, the so-called pnictogens. A short review of historical work is provided, the properties of bulk allotropes of As, Sb, and Bi discussed, and then theoretical and experimental research on mono- and few-layered arsenene, antimonene, and bismuthene addressed, discussing their structures and properties.
二维材料正在改变材料科学的研究方向。继石墨烯及其同类物，如石墨烷、氟石墨烯等被发现之后，人们对二维二元化合物的兴趣再次高涨，如金属氧化物、过渡金属二卤代物（最常以 MoS2 代表）、金属氧/氢化物硼化物和 MXenes 等。最近，人们的兴趣又转向二维单元素结构，如单层黑磷，最近还转向单层砷、锑和铋。本文简要概述了砷烯、锑烯和铋烯这三种属于第五主族元素，即所谓的磷族元素的研究领域呈指数级增长的情况。本文简短回顾了历史工作，讨论了砷、锑和铋的体各向异性的性质，然后讨论了单层和少层砷烯、锑烯和铋烯的理论和实验研究，讨论了它们的结构和性质。
