These self-organizing liquid crystals with thermotropic transitions are excellent mtallomesogens where functional properties of the transition metals such as magnetic criteria, charge conduction ability, redox, or luminous property are combined with the porous structure and wide-ranging surface area of macrocycles. This association leads to the formation of substances with promising applications across various smart electronic devices, spanning from optical displays, to drug delivery, and energy storage and conversion systems.

The ambient temperature magnetic susceptibility discovered a magnetic moment of 0.60 BM., distinctive of diamagnetic low spin Co(III) in octahedral geometry.
