Syntheses and Thermal Properties of New Liquid Crystals Bearing a Crown Ether Ring: Cation Binding in the Nematic Phase
A series of crown ether derivatives containing a biphenyl or cholesteryl moiety have been synthesized for the first time.The structural effects of these compounds on the formation of liquid-crystalline phases are discussed.We have found that benzo crown e
Nematic Liquid Crystal Compounds containing a Benzocrown Ether Unit
Benzocrown ethers carrying a para-substituted biphenyl group, (1a-c and 2a,b), display a nematic liquid crystal phase; selective complexation with picrates in the liquid crystal phase was observed by doping experiments.
