Abstract Crystal conversion of metal-organic frameworks (MOFs) between different crystal topologies on a polymer substrate has been successfully achieved by localized dissolution of MOF crystals followed by a rapid self-assembly of framework components. Upon addition of the desired organic linkers to the reaction system containing MOF crystals on the substrate, reversible crystal conversion between the [Cu2(btc)3]n and [Cu2(ndc)2(dabco)]n frameworks (btc = 1,3,5-benzene tricarboxylate, ndc = 1,4-naphthalene dicarboxylate, dabco = 1,4-diazabicyclo[2.2.2]octane) could be routinely achieved in high yields. Most surprisingly, in the case of conversion from the [Cu2(ndc)2(dabco)]n to [Cu2(btc)3]n frameworks, the [Cu2(btc)3]n crystals with unique shapes (cuboctahedron and truncated cube) could be prepared using butanol as a reaction medium.

具有不同晶体拓扑结构的金属-有机骨架之间的晶体转换，用于二维衬底上的高效晶体设计

摘要 通过 MOF 晶体的局部溶解和框架组分的快速自组装，已成功实现了聚合物基底上不同晶体拓扑结构之间金属有机框架 (MOF) 的晶体转换。将所需的有机连接体添加到基板上含有 MOF 晶体的反应体系中后，[Cu2(btc)3]n 和 [Cu2(ndc)2(dabco)]n 框架之间的可逆晶体转换 (btc = 1,3 ,5-苯三羧酸盐、ndc = 1,4-萘二羧酸盐、dabco = 1,4-二氮杂双环 [2.2.2] 辛烷) 可以常规获得高产率。最令人惊讶的是，在从 [Cu2(ndc)2(dabco)]n 转换为 [Cu2(btc)3]n 骨架的情况下，[Cu2(btc)3]n 晶体具有独特的形状（立方八面体和截断立方体） ) 可以使用丁醇作为反应介质来制备。
