| Abstract: | The liquid crystalline and selected physical properties of some vanadyl and manganese(III)-porphyrin-TCNE complexes are discussed.
These materials form linear chains from a magnetic point of view and columnar discotic LC phases. Some of the manganese complexes
exhibit a bulk magnetic phase below ∼20 K. The discussed materials are studied by means of DSC, X-ray powder diffraction,
dielectric spectroscopy, reversal current characterization and magnetic susceptibility measurements. A broader view on some
physical properties of columnar paramagnetic metallomesogens is given. |
