| 英文摘要 | A new molecular-ionic phase transition material, n-butyldiethanolammonium picrate monohydrate (beapm), which exhibits reversible switchable dielectric performances, has been successfully assembled. this compound undergoes a first-order solid-state phase transition at 160 k (t-c), which is confirmed by the thermal analyses including differential scanning calorimetry (dsc), specific heat (c-p) and dielectric measurements. variable-temperature single crystal x-ray diffraction reveals that the origin of its phase transition is ascribed to the order-disorder transformation of oxygen atoms of the poly-nitro aromatic system, i.e. the picrate anions. interestingly, the dielectric constants display clear temperature-dependant anomalies with the temperature approaching to t-c. the evident step-like anomalies of dielectric constants demonstrate two distinct states below and above the t-c, respectively. this result signifies that beapm could be conceived as a potential switchable dielectric material. these findings make us believe that beapm might be a potential solid-solid dielectric phase transition material. |
