NH2-MIL-125(Ti),　an　amine-functionalized　metal-organic-framework　(MOF),　was　found　for　the　first　time　to　exhibit　photocatalytic　activity　for　the　aerobic　selective　oxidation　of　amines　to　imines　under　visible　light　irradiations.　Different　amines　can　be　effectively　transformed　to　imines　using　O2　over　NH2-MIL-125(Ti)　under　visible　light　irradiations.　The　photo-generated　Ti3+　and　.O2-　which　was　formed　via　the　reaction　between　Ti3+　and　O2,　are　proposed　to　be　involved　in　this　transformation　process　based　on　the　experimental　observations　and　the　ESR　result.　This　work　provides　an　economical,　sustainable　and　green　process　for　amines　transformations　and　highlights　the　great　potential　of　MOFs　as　photocatalysts　for　organic　syntheses.　©　2014　Elsevier　B.V.
