A chemically assisted top-down method for the synthesis of MOF-nanoplates was developed applying amine based delamination agents. Applied on a well described model structure, the layered MOF Cu₂(bdc)₂(DMF)₂ (bdc – 1,4-benzenedicarboxylate), two different strategies of amine assisted delamination turned out to be successful to obtain nanoplates. Particles with thicknesses of around 70 nm were obtained by direct delamination of crystals using octylamine. The surfactant (polyvinylpyrrolidone) assisted synthesis combined with a post-synthetic amine delamination step enabled a further reduction of the thickness of the MOF nanoplates down to 4–14 nm.

胺辅助二维金属-有机骨架Cu ₂（bdc）₂的自上而下分层

开发了一种化学辅助的自上而下的方法，用于合成MOF纳米板，使用了胺类脱层剂。将MOF Cu ₂（bdc）₂（bdc）₂（bdc – 1,4-苯二甲酸bdc）应用于层状模型结构中，两种不同的胺辅助分层策略成功地获得了纳米板。通过使用辛胺直接分层结晶，获得厚度约为70 nm的颗粒。表面活性剂（聚乙烯吡咯烷酮）辅助的合成与合成后胺的分层步骤相结合，使MOF纳米板的厚度进一步减小至4-14 nm。
