MOF材料最新版本

金屬有機骨架材料（MOFs）的后合成修飾,報告人：劉昌2013年12月20日,2,MOFs材料簡介,20世紀90年代中期，第一代MOFs材料被合成出來,孔徑和穩(wěn)定性受到一定限制,1999年，Yaghi等人合成具有三維開放骨架結(jié)構(gòu)的MOF-5,去除孔道中的客體分子后仍然保持骨架完整,2002年，Yaghi科研組合成IRMOF系列材料,實現(xiàn)MOF材料從微孔到介孔的成功過渡,2008年，Yaghi研究組合成出上百種ZIF系列類分子篩材料,金屬離子,有機配體,配位,自組裝,周期性網(wǎng)狀骨架的多孔材料,MOFs,合成方法,特點,應(yīng)用,分類,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
