Abstract：

Porous　organic　polymers　(POPs)　are　newly　developed　porous　materials,　which　show　a　great　promise　in　gas　adsorption　and　separation,　heterogeneous　catalysis　etc.　This　work　reports　a　new　salen-(Mn)-based　porous　organic　polymer　(Mn-POP)　serving　as　a　solid　catalyst　for　heterogeneous　catalytic　olefin　epoxidation.　Mn-POP　was　synthesized　by　Sonogashira-Hagihara　reaction　when　1,3,5-triethynylbenzene　and　the　privileged　salen-(Mn)　as　monomers.　The　effective　coupling　of　these　two　monomers　was　confirmed　by　UV/Vis　and　infrared　spectroscopy.　Gas　adsorption　studies　revealed　that　Mn-POP　has　a　BET　surface　area　of　836　m2　g-1,　and　mesoporosity　(up　to　3.4　nm).　Scanning　electron　microscopy　(SEM)　showed　that　the　material　has　uniformly　spherical　shapes.　Further　olefin　epoxidation　experiments　proved　that　Mn-POP　is　a　good　solid　catalyst　for　olefin　epoxidation　with　high　activity　(up　to　99　%　conversion)　and　excellent　selectivity　(up　to　96　%)　when　O2　acts　as　oxidizer.　Moreover,　Mn-POP　catalyst　is　easily　recoverable　and　can　be　reused　for　at　least　five　times　without　loss　of　activity　and　selectivity.　©　2015　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim.
