We demonstrate by using scanning tunneling microscopy that a series of trace organic solvent additives can efficiently promote the electrically triggered phase transition of trimesic acid (TMA), which would otherwise occur rather sporadically. DFT simulations taking into account the electric field effect elucidate such tailored phase transformations, based on the Gibbs activation and free energies of the deprotonation reactions of TMA.
我们通过扫描隧道显微镜证明,一系列痕量有机溶剂添加剂能够有效地促进均苯三甲酸(TMA)的电触发相变,否则该相变只会偶尔发生。考虑电场效应的密度泛函理论(DFT)模拟基于TMA去质子化反应的吉布斯活化能和自由能阐明了这种定制的相变。
