The discotic liquid crystal radical 1 , which is very stable in the solid state or solution, has an enantiotropic ordered hexagonal columnar mesophase above room temperature with magnetic interactions among molecular spins. Radical 1 shows electrochemical amphotericity and absorption and light‐emission properties that cover the red region of the visible spectrum.
