Synthesis And Catalytic Application Of Porous Organic Polymers

With the development of science and technology,materials showing significance in human survival and development have attacted considerable attention in academic and industrial sectors,featuring as one of the three pillars of contemporary civilization.The porous organic polymers?POPs?as new functional materials include a variety of categories,such as crystalline covalent organic frameworks?COFs?and conjugated microporous polymers?CMPs?,polymer of intrinsic microporosity?PIMs?,hyper-crosslinked polymers?HCPs?,porous aromatic frameworks?PAFs?and metal-organic frameworks?MOFs?.Due to good thermal stability and chemical stability,the stable of skeletal structure and pore size,high surface area and the well defined pore structure,They exhibit enormous potential applications in energy,chemicals absorption and separation,photovoltaics,gas storage,heterogeneous catalysis,biochemical sensing and so on.Metal-organic framework UiO-67-Sal-CuCl₂,UiO-67-Sal-Cu?NO₃?₂ and UiO-67-Sal-Cu?OA_C?₂ was functionalized with hydrothermal synthesis,and the structure of three kinds MOFs was characterized via FT-IR,XRD,SEM,TEM,TGA and ICP-AES.In addition,thisthree kinds MOFs was also applied to the aerobic oxidation of various alcohols including aromatic,aliphatic,heterocyclic,etc.and good results were received.The UiO-67-CuCl₂ could be recovered easily and recycled up to four times in the oxidation of benzyl alcohol without significant loss of catalytic activity and selectivity.Metal-organic framework Cu?BTC?was functionalized with hydrothermal synthesis,and the structure of two kinds MOFs was characterized via XRD,TGA and the nitrogen adsorption–desorption isotherms.In addition,this kind MOFs was also applied to the aerobic oxidation of various alcohols including aromatic,aliphatic,heterocyclic,etc.and good results were received.The CuBTC show the good catalytic activity and selectivity.
