Iminoxyl biradical may be useful biradical spin probe for the investigation of the dynamic distribution of the directors in some liquid crystal. The iminoxyl biradical has been synthesized by a new convenient method and the intermediate products of each step were identified by the measurement of melting point and spectroscopic methods such as IR, UV, NMR and Mass spectrometry. The final product, iminoxyl biradical, was identified by the electron paramagnetic resonance spectroscopy and the interaction between two spins of the radical was discussed based on the EPR peaks.
