Investigating the hydrogen-bonded organic frameworks (HOFs) with intrinsic functions has been a great challenge for the development of HOF materials. In this paper, an efficient way of obtaining a HOF with intrinsic catalytic activity is presented. A microporous HOF-PyTTA was self-assembled by using 4,4',4'',4'''-(pyrene-1,3,6,8-tetrayl) tetraaniline (PyTTA) as an organic monomer. The monomer has a pyrene ring with a conjugated structure, which is conducive to the construction of large-area π-π interactions, therefore improving the stability of the HOF structure. The amino-functional group of the monomer serves as the active site which enables the HOF-PyTTA, which acts as a non-metallic catalyst to catalyze the conversion of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP). The permanent pore structure of the HOF-PyTTA was confirmed by X-ray single-crystal diffraction and CO₂ isotherm adsorption experiments. To broaden the application of HOF-PyTTA, we propose growing HOF-PyTTA on the filter membranes of diverse materials and making a catalytic column by filling the HOF-PyTTA/glass fiber membrane into the syringe. After pouring the mixture of 4-NP and NaBH₄ into the catalytic column, 4-NP was converted into 4-AP with a high rate of conversion. This work develops a simple, robust, and flexible HOF with intrinsic catalytic reduction activity for 4-NP, and broadens the application of HOF for functional modification and catalytic application.

研究具有内在功能的氢键有机骨架（HOFs）一直是开发HOF材料的一大挑战。在本文中，提出了一种获得具有内在催化活性的 HOF 的有效方法。以 4,4',4'',4'''-(pyrene-1,3,6,8-tetrayl) 四苯胺 (PyTTA) 作为有机单体，自组装微孔 HOF-PyTTA。该单体具有共轭结构的芘环，有利于构建大面积的π-π相互作用，从而提高HOF结构的稳定性。单体的氨基官能团作为活性位点，使 HOF-PyTTA 作为非金属催化剂催化 4-硝基苯酚 (4-NP) 转化为 4-氨基苯酚 (4-AP) .₂等温吸附实验。为了拓宽 HOF-PyTTA 的应用，我们建议在不同材料的滤膜上生长 HOF-PyTTA，并通过将 HOF-PyTTA/玻璃纤维膜填充到注射器中来制作催化柱。将4-NP和NaBH ₄的混合物倒入催化柱后，4-NP以高转化率转化为4-AP。这项工作开发了一种简单、稳健、灵活的 HOF，对 4-NP 具有内在的催化还原活性，并拓宽了 HOF 在功能修饰和催化应用中的应用。
