纳米结构材料的可编程合成和增材三维（3D）制造的同步发展为制造新型材料和器件创造了丰富而令人兴奋的机会空间。特别是，用介孔材料制造复杂的分层器件几何形状提出了几个科学上有趣和技术上相关的挑战。在这里，我们展示了如何对具有12个甲基丙烯酸配体的甲基丙烯酸氧锆簇定义的光响应构建块进行数字光处理，以创建具有多层多孔网络特征的复杂上层结构。受到自然界中普遍存在的类似复杂的3D分层介孔结构的启发，我们展示了3D叶片的制造作为概念证明。这项工作展示了在无机建筑模块，介孔材料和3D数字光处理的交叉点出现的令人兴奋的机会空间，为创建具有复杂几何形状的功能分层上层结构和设备开辟了新的途径。
Concurrent advances in the programmable synthesis of nanostructured materials and additive three-dimensional (3D) manufacturing have created a rich and exciting opportunity space to fabricate novel materials and devices. In particular, creating complex hierarchical device geometries from mesoporous materials presents several scientifically interesting and technologically relevant challenges. Here, we show how digital light processing of photoresponsive building block defined by an oxozirconium methacrylate cluster with 12 methacrylic acid ligands can be used to enable the creation of complex superstructures characterized by multilevel porous networks. Inspired by similarly complex 3D hierarchical mesoporous structures ubiquitous in nature, we demonstrated the fabrication of a 3D leaf as a proof of concept. This work demonstrates how exciting opportunity space emerging at the intersection of inorganic building blocks, mesoporous materials, and 3D digital light processing opens new pathways to create functional hierarchical superstructures and devices with complex geometries.
