摘　　要：作为晶态杂化多孔材料,金属-有机框架(metal-organic frameworks, MOFs)材料因其高比表面积与孔体积等优点在诸多应用领域取得了重要的研究进展.然而,此类材料所存在的水稳定性差等问题,严重限制了其实际工业应用.为此研究者提出了多种构建疏水MOFs材料的合成策略,其中合成后修饰是一种重要的实现方法.本文将MOFs材料的合成后疏水修饰分为四类,即配体功能化修饰、金属位点功能化修饰、颗粒外表面修饰与其他方法等,综述了合成后修饰构筑疏水MOFs材料的研究进展,并对疏水MOFs材料进行了总结与展望.As a type of crystalline porous hybrid materials, metal-organic frameworks(MOFs) have exhibited significant progress in many fields because of their unique properties, such as high specific area and pore volume.However, the low water stability of MOFs hinders the further practical applications. In order to address the drawback,several strategies have been proposed to fabricate hydrophobic MOFs, among which the postsynthetic modification(PSM) is an important option. The synthesis of hydrophobic MOFs by PSM has been classified into four types, namely ligand functionalization, metal site functionalization, external surface modification and other pathways. The present review summarizes the advances in the synthesis and applications of hydrophobic MOFs by PSM, and further provides a brief outlook of this realm.
