Abstract


In the past decade, the research work on behalf of List and MacMillan promote organic small molecule catalytic flourish, making it one of the emerging research directions in the field of asymmetric catalysis. But Organocatalyst often larger amount, and expensive, difficult to recycle;. Heterogeneous catalysts by small organic molecules is an effective way to solve these problems. Multiphase Organocatalyst many ways, immobilized to magnetic nanomaterials, mesoporous materials and polymer resin. On the other hand, the recent development of the inherent microporous polymer conjugated microporous polymer with its excellent nature of the hole, the advantages of thermal stability and chemical stability of the organic skeleton attention. But there is no Organocatalyst research combined with organic microporous material been reported. If the small organic molecules may be catalyst implanted into the skeleton of the organic microporous polymeric material or within the pores, the resulting material will not only having excellent pore properties conducive to the heterogeneous catalytic reaction of the mass transfer, to improve the efficiency of catalytic reaction; but by co valence bond connecting a heterogeneous catalyst to avoid the loss of catalytic activity center, and to improve the stability of the catalyst. Solid small organic molecules having a microporous nature catalyst will be possible in the industrial production has application prospects. This thesis work is primarily designed and synthesized several skeleton hetero atoms and functional groups conjugated microporous polymer material designed and synthesized several functional organic microporous catalyst containing small organic molecules, and on this basis, the polymerization physical materials, such as nitrogen temperature absorption desorption, solid state NMR characterization methods were characterized by the synthesis of organic microporous material, and preliminary studies of organic microporous polymer materials in heterogeneous catalysis. Microporous materials development process, the first chapter of this thesis highlights organic microporous polymer materials development process, and in recent years a new type of organic microporous materials in heterogeneous catalysis, gas storage and separation applications . Chapter II Chapter III of this dissertation aims the skeleton modified conjugated microporous polymer material and structural modification. Chapter II respectively triiodide aniline and triphenyl boron bromide synthesized as a precursor of nitrogen atoms and boron atoms contained in the skeleton conjugated microporous polymer, such as nitrogen temperature by adsorption and desorption, and solid state NMR characterization means. These materials were characterized. Chapter containing nitro (-NO2) and methoxy (-OCH3) precursor synthesized containing these two functional groups conjugated microporous polymer material and its characterization. In the fourth chapter of this thesis, we first synthesized containing small organic molecules catalyst L-proline, (R)-BINOL and (R)-BINOL phosphoric three organic molecules precursors, then Sonogashira-Hagihara even linking reaction synthesis of a preliminary study of a series of small organic molecules conjugated microporous polymers, catalysts and their characterization and catalytic reaction performance. In the fifth chapter of this thesis, we Sonogashira-Hagihara coupling reaction of Tege Le alkali introduction of the skeleton of the organic microporous polymer materials which, through a variety of characterization methods to characterize the structure and microporous nature, and research its hydrogen storage capacity as well as a heterogeneous catalyst in the catalytic effect of addition reaction of diethylzinc to benzaldehyde.
