Reduction of the transition temperatures in mesomorphic lanthanide complexes by the exchange of counter-ions

Abstract

Metathesis of the chloride anion in the mesomorphic lanthanide complexes [LnL(LH)2 ][Cl]2 (LH=salicylaldimine; Ln=lanthanide element) by dodecyl sulfate (DOS) leads to the complexes [LnL(LH)2 ][DOS]2 , which have wider mesomorphic ranges and lower clearing points.
