Ferrocenium ionic liquids containing 3,4,5-tri(dodecyloxy)benzene sulfonate and bis(2-ethylhexyl)sulfosuccinate (AOT) anions
摘要:
The salts of the dodecyloctamethylferrocenium cation (1) and decamethylferrocenium cation (2) with the mesogenic anions of 3,4,5-tri(dodecyloxy)benzene sulfonate [(C12H25O)(3)C6H2SO3] and bis(2-ethylhexyl)sulfosuccinate (AOT) were prepared. The resulting materials, [1][(C12H25O)(3)C6H2SO3], [2] [(C12H25O)(3)C6H2SO3], and [1][AOT] were ionic liquids exhibiting glass transitions at -53, -41, and -51 degrees C, respectively, whereas [2][AOT] was a solid with a high melting point (T-m = 122 degrees C). The melting points and glass transition temperatures correlated with the flexibility of the substituents and the size of the constituent molecules. None of the salts exhibited liquid crystal phases.
