Treatment of textile water containing organic molecules as contaminants still remains a challenge and has become a central issue for environment remediation. Here, a nucleotide incorporated zeolitic imidazolate frameworks (NZIF) featuring hierarchically porous structure served as a potential adsorbent for removal of organic dye molecules. Adsorption isotherms of organic dyes were accurately described by Langmuir adsorption model with correlation coefficients of 0.98 and kinetic data followed the pseudo-second-order model. The maximum adsorption capacity of NZIF for Congo red (CR) and methylene blue (MB) reached 769 and 10 mg/g, respectively, which were 6 and 5 times higher than that of ZIF-8. The adsorption behavior of sunset yellow and crystal violet was examined for mechanism investigation. Analysis of pore size, molecular size, zeta potential and FTIR measurement together revealed that mesopores in NZIF provided more interaction sites and led to enhanced adsorption capacity. Hydrogen bonding and π-π stacking which resulted from the interaction between introduced nucleotide monophosphate and dyes dominated the driving forces for adsorption, where electrostatic interaction was also involved. Moreover, the introduced nucleoside monophosphate enabled NZIF to function under acidic condition whereas ZIF-8 collapsed. This study opens a new avenue for design of porous materials for environment remediation.

含有有机分子作为污染物的纺织品水的处理仍然是一个挑战，并已成为环境修复的中心问题。在此，具有分级多孔结构特征的掺入核苷酸的沸石咪唑酸盐骨架（NZIF）用作去除有机染料分子的潜在吸附剂。用Langmuir吸附模型精确描述有机染料的吸附等温线，相关系数为0.98，动力学数据遵循伪二级模型。NZIF对刚果红（CR）和亚甲基蓝（MB）的最大吸附容量分别达到769和10 mg / g，分别比ZIF-8高6和5倍。研究了日落黄和结晶紫的吸附行为，用于机理研究。分析孔径，分子大小，Zeta电位和FTIR测量共同显示NZIF中的中孔提供了更多的相互作用位点，并提高了吸附能力。氢键和π-π堆积是由引入的核苷酸单磷酸酯和染料之间的相互作用引起的，在吸附的驱动力中占主导地位，其中还涉及静电相互作用。此外，引入的核苷一磷酸使NZIF能够在酸性条件下发挥作用，而ZIF-8却崩溃了。这项研究为设计用于环境修复的多孔材料开辟了一条新途径。氢键和π-π堆积是由引入的核苷酸单磷酸酯和染料之间的相互作用引起的，在吸附的驱动力中占主导地位，其中还涉及静电相互作用。此外，引入的核苷一磷酸使NZIF能够在酸性条件下发挥作用，而ZIF-8却崩溃了。这项研究为设计用于环境修复的多孔材料开辟了一条新途径。氢键和π-π堆积是由引入的核苷酸单磷酸酯和染料之间的相互作用引起的，在吸附的驱动力中占主导地位，其中还涉及静电相互作用。此外，引入的核苷一磷酸使NZIF能够在酸性条件下发挥作用，而ZIF-8却崩溃了。这项研究为设计用于环境修复的多孔材料开辟了一条新途径。
