Liquid crystalline 2D borophene oxide for inorganic optical devices.

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.

Solution Phase Mass Synthesis of 2D Atomic Layer with Hexagonal Boron Network.

Borophene and the analogs are attractive 2D-materials showing unique mechanical and electronic properties. In this study, the bottom-up synthesis of an atomic boron network possessing a completely planar skeleton was achieved from KBH. The borophene-analog was stabilized by oxygen atoms positioned on the same plane, providing holes and the anionic state of the layer.
