  • Patent number: 8709280
    Abstract: Polar nematic compounds having the following structure: where is a caged boron structure. The sphere of the caged boron structure is C and each non-sphere vertex of the caged boron structure is B—H. R is H, an alkyl, a cycloalkyl, a bicycloalkyl, an alkenyl, a cycloalkenyl, a bicycloalkenyl, an alkynyl, an acyl, an aryl, an alkylaryl, a halogen, a cyano group, an isothiocyanoto group, or a group that forms an ether, a ketone, an ester, a thioester, a sulfide, or a sulfone. R? is H, an alkyl, a cycloalkyl, a bicycloalkyl, an alkenyl, a cycloalkenyl, a bicycloalkenyl, an alkynyl, an aryl, an alkylaryl, or a halogen. The compounds may be used in liquid crystal displays, and in television sets, laptop computers, computer monitors, hand-held communication devices, gaming devices, watches, cash registers, clocks, and calculators having liquid crystal displays.
