Borophene has been recently proposed as a next-generation two-dimensional material with promising electronic and optical properties. However, its instability has thus far limited its large-scale applications. Here, we investigate a liquid-state borophene analogue with an ordered layer structure derived from two-dimensional borophene oxide. The material structure, phase transition features and basic properties are revealed by using X-ray analysis, optical and electron microscopy, and thermal characterization. The obtained liquid crystal exhibits high thermal stability at temperatures up to 350 °C and an optical switching behaviour driven by a low voltage of 1 V.
硼烯最近被提议作为一种具有有前景的电子和光学特性的下一代二维材料。然而,其不稳定性迄今为止限制了它的大规模应用。在此,我们研究了一种具有由二维氧化硼衍生而来的有序层状结构的液态硼烯类似物。通过使用X射线分析、光学和电子显微镜以及热表征揭示了该材料的结构、相变特征和基本性质。所获得的液晶在高达350°C的温度下表现出高的热稳定性,并具有由1V的低电压驱动的光学开关行为。
