Thermochromic nitroxide : A nitroxide radical (AZADO) exhibits thermochromism with a structural change from a dimer at low temperature (4 °C) to paired monomers with large antiferromagnetic interaction at high temperature (35 °C). An hysteresis loop is observed in the magnetic data of this compound, revealing it to exhibit a first‐order phase transition with room‐temperature magnetic bistability.
