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

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 7F1 multiplet in the corresponding e...

Description
Summary: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 7F1 multiplet in the corresponding europium(III) compounds. A method to rapidly measure this splitting value is accessible through photoluminescence measurements.
