一种新的酶模拟体系——催化性金属-有机络合聚合物

A Novel Enzyme-mimic System——Catalytic Metal-organic Coordination Polymers

综述了近来出现的一类新的多孔材料——金属-有机络合聚合物(MOCP)催化功能的设计策略及合成途径。通过配体结构的选择或修饰可得到催化性的孔环境或采用适当的合成策略使过渡金属离子保留不饱和位点,结合MOCP孔道对分子的择形和筛分作用,赋予MOCP以酶样催化功能,从而得到一种新的酶模拟体系——催化性金属-有机络合聚合物(cMOCPs)。cMOCPs在择形催化,尤其在不对称催化应用方面具有诱人前景,也给设计新型催化剂提供了一个新的思路。

Approaches to designing and synthesizing a class of promising functional porous materials arising recently, catalytic metal-organic coordination polymers （cMOCPs） are reviewed in the paper. It is possible to endow MOCPs with enzyme-like catalytic property by selecting proper ligands or by decorating ligands with catalytic groups or by making transltion-metal ions of MOCPs retain open sites with the help of suitable synthesis strategies, combined with native molecule-sieving and molecule-selecting function of MOCPs. In those ways, cMOCPs-a novel enzyme mimic system can be obtained, which displays an attractive potential in shape-selected catalysis, especially, in asymmetry catalysis and provides us with a fire-new clue for the design of new-type catalyzers.
