  • Anionic imide material having ferromagnetism at room temperature and the use thereof
    Patent number: 11084816
    Abstract: The anionic imide material is obtained by preparing a solution or a suspension of an imide compound, then reducing and drying the same; the anionic material comprises anions of an imide compound, the anions being at least one selected from the following formula I or formula II; in formula I or II: n=1, 2, or 3; R1, R2 are respectively selected from at least one of H, amino, carboxyl, hydroxy, thiol, and pyridyl groups; X1-X4 are respectively an electron withdrawing group, and specifically selected from one of H, F, Cl, Br, CN, and NO2 groups. The anionic material of the present invention has a Curie temperature larger than room temperature and ferromagnetism, and is an organic magnetic material; it may be used for preparing an organic magnetic material and/or an organic magnetic device.
