The development of efficient catalysts for the selective oxidation of hydrocarbons in the presence of molecular oxygen under mild condition has remained to be a difficult challenge to the catalytic science.In this thesis, much attention has been paid to synthesis and catalytic oxidation properties of a new type of polymeric center-quasi-porphyrin-crown ether binuclear complex in which porphyrin or Salen Schiff base and crown ethers are combined in one polymer. As our respect, the function of complexes will ...
