The chain- and ribbon-like structural hierarchies are used to design two nanoporous polymorphs composed of only four-member and six-member rings of ZnO as primary building blocks in cubic lattice frameworks. Specifically, the bottom-up polymeric assembly of these small simple clusters into high cubic symmetric phases is considered, with energetic, dynamic, and mechanical stabilities proven by density-functional-based calculations. Both phases are rivaling with those of known cage-like nanoporous polymorphs in many porous characteristics while preserving an intrinsic wide bandgap from ZnO tetragonal bonding. Furthermore, the design scheme is feasible to apply with different morphology motifs or extend to more cluster prototypes and materials.

立方晶格中新型链状和带状 ZnO 纳米多孔结晶相

链状和带状结构层次用于设计仅由四元和六元 ZnO 环组成的两种纳米多孔多晶型物，作为立方晶格框架中的主要构建块。具体而言，考虑了这些小的简单簇自下而上的聚合组装成高立方对称相，并通过基于密度泛函的计算证明了其能量、动态和机械稳定性。两相在许多多孔特性方面都与已知的笼状纳米多孔多晶型物相媲美，同时保留了 ZnO 四方键合的固有宽带隙。此外，该设计方案适用于不同的形态图案或扩展到更多的集群原型和材料。
