Synthesis And Properties Of Ferrocene-porphyrin-fullerene Polymer Linked By Metal Axial Coordination

In recently years,to make better use of solar energy,an increasing number of scientists have begun to pay attention to artificial photosynthesic systems and photoelectric conversion systems.Porphyrins refer to a class of electron donors with good electrochemical properties.They can form different kinds of donor-receptor system linked to electron acceptors,which have potential application in the fields of organic solar cell and organic photoelectric materials.In order to construct such a system,this study introduced electron donor porphyrins,ferrocenes,and electron acceptors fullerene through various reactions.In the meanwhile,the Click reaction was also introduced to increase the reaction efficiency.Considering the solubility of polymers,we have also introduced long-chain alkyl groups to improve the solubility of polymers.We have designed and synthesized three kinds of polymers,characterized by GPC NMR,HRMS,IR.The study shows that the introduction of ferrocene led to a stronger fluorescence quenching.The result shows that there exists a strong electron or energy transfer among ferrocene and porphyrin ring.Therefore.these compounds have application value in the field of photoelectric conversion materials.
