介孔金属-有机框架(MesoMOFs)的合成研究进展

Research Progress on Synthesis of Mesoporous Metal-organic Frameworks(MesoMOFs)

作为未来材料之星的金属-有机框架(Metal-organic frameworks: MOFs),是一类由金属中心或无机簇与有机配体通过配位键桥联而成的高度有序的结晶型多孔材料,与传统的孔材料相比,具有结构、功能和孔径可调等特点,就孔径而言,可以从微孔扩展到介孔范围。本文综述了近年来介孔金属-有机框架(MesoMOFs)的主要合成研究进展,详细探讨了配体有机链节拓展法(Extension of the organic linkers)、规模扩展法(The scale chemistry strategy)、配体交换法(Stepwise ligand exchange)和能量诱导转化法(Energy-induced conversion)等合成策略。

Owing to their unique structure and special properties, the metal-organic frameworks (MOFs) recently have attracted much scientific interest in the field material, in which the metal centers or inorganic clusters as the linkers are connected by organic ligands to form the highly ordered pore structure. Be different from the conventional pore materials, the pore sizes, structure and properties of MOFs can be adjusted through molecular design. As far as the pore sizes, it can be extended from micropores to mesopores. In this contribution, the main strategies for synthesis the Mesoporous MOFs such as extension of the organic linkers, the scale chemistry strategy, stepwise ligand exchange and energy-induced conversion were summarized.
