Patent number: 8709280Abstract: 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.Type: GrantFiled: April 26, 2012Date of Patent: April 29, 2014Assignee: Vanderbilt UniversityInventors: Bryan Ringstrand, Piotr Kaszynski

Patent number: 5405550Abstract: Molecular bulding beams, liquid crystals, and surfactants in the form of compounds based on [1.1.1]propellane, including poly[1.1.1]propellanes. Molecular building beams having a telomeric or polymeric chain staff, and linking groups functionalized on one or both ends of the staff. A system for linking the beams to connecting units to construct molecular structures of various forms, such as whips, combs, scaffoldings, nets, or stars. Other broad aspects of the invention provide liquid crystals and surfactants. The liquid crystals include telomeric or polymeric compounds functionalized with flexible end groups, while the surfactant compounds are functionalized with surface active end groups. Methods of synthesizing the various compounds ar also provided.Type: GrantFiled: August 10, 1992Date of Patent: April 11, 1995Assignee: Josef MichlInventors: Josef Michl, Piotr Kaszynski, Andrienne C.
