【摘要】 我们通过传统的水溶液合成或环境友好的机械化学研磨合成方法,首次使用磺酸盐和N-供体配体,无需溶剂,合成了两种新的氢键有机骨架材料。形成的氢键有机骨架通过酸碱对相互作用,表现出高达10-2Scm-1的高质子传导率值。密度泛函理论计算的结果证明两分子的正负极性中心分离且通过诱导力相互作用。此外,接触角测量和场发射扫描电子显微镜也被用来解释影响化合物质子传导的外部因素,如晶粒大小和表面的粗糙程度。更多还原

【Abstract】 Two new HOFs materials have been synthesized via traditional aqueous solution synthesis or environmentallyfriendly mechanochemical grinding synthesis method by using sulfonate and N-donor ligands for the first time without solvent. The formed HOFs exhibited high proton conductivity value up to 10-2 S cm-1 through acid-base pairs. The results of the density functional theory calculations proved that 2 should have higher proton conductivity. In addition, contact angles measurements and field-emission scanning electron microscopy were also used to explain the discrepancy of proton conduction of the compounds synthesized by different methods.更多还原
