| Outline of Final Research Achievements |
In order to control the state of electron spins in the electron-transporting amorphous thin film, novel stable neutral radical-substituted electron-transporting molecular materials were developed, in which tert-butyl nitroxide was introduced into 2,4,6-tri-phenyl-1,3,5-triazine of the electron-accepting moiety with m-phenylene-type linkage. By means of in-situ measurements of cyclic voltammetry and continuous wave-electron spin resonance spectrum at a low temperature, ferromagnetic exchange interaction (J > 0) between the anion radical on the triazine-acceptor moiety and the nitroxide radical was detected in a solution state. For application to thin-film devices, fabrication of amorphous thin films from the solution was performed by spin-coating method. The amorphous state of the obtained thin films was revealed by XRD measurements and AFM observations.
