Ioneneomeric Liquid Crystals
A new class of liquid crystals based on salts of the 1,1-dialkyl–4,4’-bipyridinium core are reported. Mesophase transition temperatures and stability ranges depend on both the nature of the anion and the length of the alkyl chain. Polymeric versions of these mesogens can be synthesized which retain electrochronic properties.
