Polar nematic compounds, one example of which has the following structure: is a caged boron structure, where 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, or an isothiocyanoto group, or R is a group that forms an ether, a ketone, an ester, a thioester, a sulfide, or a sulfone. X is COOR′ or COSR′. R′ is H, an alkyl, a cycloalkyl, a bicycloalkyl, an alkenyl, a cycloalkenyl, a bicycloalkenyl, an alkynyl, an aryl, a halogen, or a cyano group. The compounds may be used in liquid crystal displays (LCDs), and in television sets, laptop computers, computer monitors, hand-held communication devices, gaming devices, watches, cash registers, clocks, and calculators having liquid crystal displays.
