摘要

采用室温无溶剂机械化学研磨法制备了三种热稳定性和化学稳定性均较高的等孔共价有机骨架(COFs)。将这些COFs与溶剂热合成的COFs进行了各方面的比较。这些无溶剂机械化学合成的COFs结晶度适中，在沸水、酸(9 N HCl)和碱[3 N NaOH中的TpBD (MC)和9 N NaOH中的TpPa-2 (MC)]中具有良好的稳定性。在机械化学合成过程中，COF层的剥落与COF的形成同时进行。由此获得的结构似乎具有类似石墨烯的层状形态(剥离层)，与溶剂热合成的母体COFs不同。

Mechanochemical Synthesis of Chemically Stable Isoreticular Covalent Organic Frameworks

Three thermally and chemically stable isoreticular covalent organic frameworks (COFs) were synthesized via room-temperature solvent-free mechanochemical grinding. These COFs were successfully compared with their solvothermally synthesized counterparts in all aspects. These solvent-free mechanochemically synthesized COFs have moderate crystallinity with remarkable stability in boiling water, acid (9 N HCl), and base [TpBD (MC) in 3 N NaOH and TpPa-2 (MC) in 9 N NaOH]. Exfoliation of COF layers was simultaneously observed with COF formation during mechanochemical synthesis. The structures thus obtained seemed to have a graphene-like layered morphology (exfoliated layers), unlike the parent COFs synthesized solvothermally.
