论文摘要
如果单个瓷砖装饰以降低其对称性，则周期性的瓷砖可以存储信息。 Truchet瓷砖 - 此类瓷砖的广泛空间填充布置 - 提供了与条形码和QR码相关的视觉数据存储的有效机制。在这里，我们证明了结晶金属有机框架[OZN $ _4 $] [1,3-苯并二羧酸盐] $ _ 3 $（trumof-1）是一个原子级实现，可以实现复杂的三维曲盘瓷砖。它的晶体结构由定期安排的含锌簇的相同组成组成，该簇以明确但无序的方式均匀连接，以提供拓扑上的微孔网络。我们建议这种异常结构是由于几何建筑单元组装的几何挫败感而出现的。
Periodic tilings can store information if individual tiles are decorated to lower their symmetry. Truchet tilings - the broad family of space-filling arrangements of such tiles - offer an efficient mechanism of visual data storage related to that used in barcodes and QR codes. Here, we show that the crystalline metal-organic framework [OZn$_4$][1,3-benzenedicarboxylate]$_3$ (TRUMOF-1) is an atomic-scale realisation of a complex three-dimensional Truchet tiling. Its crystal structure consists of a periodically-arranged assembly of identical zinc-containing clusters connected uniformly in a well-defined but disordered fashion to give a topologically aperiodic microporous network. We suggest that this unusual structure emerges as a consequence of geometric frustration in the chemical building units from which it is assembled.
