Probing the Magnetic Anisotropy of Lanthanide‐Containing Metallomesogens by Luminescence Spectroscopy

Abstract
The alignment of liquid crystals through magnetism demands a high value of the magnetic anisotropy. The magnitude of the anisotropy for a series of isostructural lanthanide-containing metallomesogens can be estimated on basis of the crystal-field splitting of the (7)F1 multiplet in the corresponding europium(III) compounds. A method to rapidly measure this splitting value is accessible through photoluminescence measurements.
