Colloidal crystals have shown great potential as versatile templates for the fabrication of patterned micro- and nanostructures with complex architectures and novel properties. The patterning of functional crystalline materials in two and three dimensions is essential to the realization of their applications in many technologically important fields. This article highlights some recent progress in the fabrication of 2D and 3D patterned crystalline materials with the assistance of colloidal crystals. By combining a bioinspired synthetic strategy based on a transient amorphous phase with a colloidal-crystal templating method, unique 3D ordered macroporous (3DOM) calcite single crystals can be created. Moreover, patterned arrays of regular ZnO nanopillars with controlled size, shape, and orientation can be fabricated via a facile wet chemical approach by using masks derived from monolayer colloidal crystals (MCC).
胶体晶体作为一种通用模板，在制备具有复杂结构和新颖性能的图案化微纳米结构方面显示出巨大的潜力。在二维和三维空间中对功能晶体材料进行图案化对于实现它们在许多重要技术领域的应用至关重要。本文重点介绍了在胶体晶体辅助下制备二维和三维图案化晶体材料的一些最新进展。通过将基于瞬态非晶相的仿生合成策略与胶体晶体模板法相结合，可以制备独特的 3D 有序大孔（3DOM）方解石单晶。此外，还可以通过简便的湿化学方法，利用源自单层胶体晶体（MCC）的掩模，制备具有可控尺寸、形状和取向的规则 ZnO 纳米柱图案阵列。
