Few‐layer and monolayer arsenic (arsenene) materials have been attracting great attention mainly from a theoretical perspective. Chemical modification of these materials would expand significantly the range of their applications. Here, we describe a chlorocarbene‐mediated modification of exfoliated layered arsenic materials. Carbene‐based species are highly reactive and offer further possibilities of functionalization. Our approach for modifying the arsenic surface by chlorocarbene generated from organolithium and dichloromethane resulted in a large surface coverage and a highly luminescent functionalized material, opening the door for its application in modern optoelectronic devices.

脱落碳与氯卡宾的共价官能化

主要从理论的角度来看，很少有几层和单层砷（砷）材料引起了极大的关注。这些材料的化学改性将大大扩展其应用范围。在这里，我们描述了剥落的分层砷材料的氯卡宾介导的修饰。基于碳的物质具有高反应性，并提供了进一步的功能化可能性。我们通过有机锂和二氯甲烷生成的氯卡宾对砷表面进行改性的方法导致了较大的表面覆盖率和高度发光的功能化材料，这为其在现代光电设备中的应用打开了方便之门。
