摘要：

The mesophase behaviour of homologues N-(n-alkyl) pyridinium hydrogensulfates has been examined by thermal and optical studies. These cationic surfactants not only form thermotropic mesophases at relatively low temperatures (about 100 degrees C), but also form lyotropic mesophases in the unconventional solvent concentrated sulphuric acid. The sequences of lyotropic liquid crystalline phases have been determined. (C) 1999 Elsevier Science B.V. All rights reserved.
