MOF材料最新版本

金属有机骨架材料（MOFs）的后合成修饰,报告人：刘昌2013年12月20日,2,MOFs材料简介,20世纪90年代中期，第一代MOFs材料被合成出来,孔径和稳定性受到一定限制,1999年，Yaghi等人合成具有三维开放骨架结构的MOF-5,去除孔道中的客体分子后仍然保持骨架完整,2002年，Yaghi科研组合成IRMOF系列材料,实现MOF材料从微孔到介孔的成功过渡,2008年，Yaghi研究组合成出上百种ZIF系列类分子筛材料,金属离子,有机配体,配位,自组装,周期性网状骨架的多孔材料,MOFs,合成方法,特点,应用,分类,Eddaoudi,M.Kim,J.Rosi,N.Vodak,D.OKeeffe,M.Yaghi,O.M.science295,469-472(2002),Thechoiceofmetalionsandorganicligandcandictatetheframeworktopology(affectingporeandshape)andinfluencetheoverallchemicalfunctionalityoftheframework.,KyoSungPark,ZhengNi,AdrienP.PNAS2006;103;10186-10191,IRMOF-3(IsoreticularMetalOrganicFramework-3)isonesuchMOF,whichcontainsaminegroupsliningtheporesoftheframework.,GenericschemeforthepreparationofafunctionalizedMOFbyusingdirectsolvothermalsynthesis.,M.Eddaoudi,J.Kim,N.Rosi,D.Vodak,J.Wachter,M.OKeeffeandO.M.Yaghi,Science,2002,295,469472.,Organicligands(linkers,left),scaffoldrepresentation(middle),andlatticestructure(fromX-raydata,right),Agenericschemeforthepostsyntheticmodification(PSM)ofMOFs(top).AspecificexampleofPSMonIRMOF-3withbenzoicanhydride(bottom).,NewPSMreactions,IncreasingandcontrollingfunctionalityviaPSM,1.HowmanydifferentfunctionalgroupscanbeincorporatedintoaMOF2.Howthespatiallocalizationcanbecontrolled,S.J.Garibay,Z.Wang,K.K.TanabeandS.M.Cohen,Inorg.Chem.,2009,48,73417349.,T.Gadzikwa,O.K.Farha,C.D.Malliakas,M.G.Kanatzidis,J.T.HuppandS.T.Nguyen,J.Am.Chem.Soc.,2009,131,1361313615.,Bytakingadvantageofsolventmoleculestrappedwithintheframework,theabilitytodistinguishtheexteriorandinterioroftheMOFwasachieved.,17,MetalsandcoordinatecovalentmodificationviaPSM,K.Oisaki,Q.Li,H.Furukawa,A.U.CzajaandO.M.Yaghi,J.Am.Chem.Soc.,2010,132,92629264.,Inthisstrategy,theMOFisappendedwithachelatinggroupandmetallatedafterwards.,19,ImprovingandmodulatinggassorptionviaPSM,Z.Wang,K.K.TanabeandS.M.Cohen,Chem.Eur.J.,2010,16,212217.,MOFcatalystsviaPSM,CoordinatecovalentmodificationofMIL-101(Cr)withchiralprolineligands.CoordinatecovalentmodificationofMIL-101(Cr)atvacan
