Graphical Abstract
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.
