  • Patent number: 11795059
    Abstract: Provided are an atomic layer sheet that contains boron and oxygen as framework elements, is networked by nonequilibrium couplings having boron-boron bonds, and has a molar ratio of oxygen to boron (oxygen/boron) of less than 1.5, a laminated sheet containing a plurality of such atomic layer sheets and metal ions between ones of the sheets, and a thermotropic liquid crystal and a lyotropic liquid crystal containing these. In addition, there is provided a method for manufacturing an atomic layer sheet and/or a laminated sheet containing boron and oxygen, the method including: adding MBH4, where M represents an alkali metal ion, into a solvent containing an organic solvent in an inert gas atmosphere to prepare a solution; and exposing the solution to an atmosphere containing oxygen.
