The applications of covalent crystalline materials face a chronic challenge of the efficient and precise construction of a highly or single-crystalline product by polymerization, especially for three-dimensional covalent organic frameworks (3D COFs) featuring highly complex crystalline porous structures. Here, we demonstrate the first example of minutes growth of 3D COF single crystals, in which supercritical CO2 as the solvent extremely accelerates the precise construction of 3D covalent networks. The crystal growth rate of 3D COFs reaches 35 μm min–1, and single crystals with sizes up to 110 μm are polymerized within 1–5 min, which have unique optical properties such as polarized photoluminescence, polarized second-harmonic generation, and so on. Considering this, as well as environmental friendliness and industrial compatibility, the supercritically solvothermal polymerization holds great promise in future applications.

单晶三维共价有机骨架的超快速合成及其在偏振光学中的应用
共价晶体材料的应用面临着通过聚合有效和精确地构建高度或单晶产品的长期挑战，特别是对于具有高度复杂的晶体多孔结构的三维共价有机框架（3D COF）。在这里，我们展示了第一个分钟生长 3D COF 单晶的例子，其中超临界 CO 2作为溶剂极大地加速了 3D 共价网络的精确构建。3D COFs 的晶体生长速率达到 35 μm min –1，尺寸达110 μm的单晶在1-5 min内聚合，具有偏振光致发光、偏振二次谐波产生等独特的光学性质。考虑到这一点，以及环境友好性和工业相容性，超临界溶剂热聚合在未来的应用中具有很大的前景。
