碩士 === 國立臺灣師範大學 === 化學系 === 105 === In light of the fact that boronic acids can react with polyols to form stable boronate esters, we devoted effort to modifying 3-aminophenylboronic acid (denoted APBA)and bis(2,2'-bipyridine)-[1,10-phenanthroline-5,6-dione] ruthenate(II) (denoted Ru(bpy)2(phen-dione)2+) on carbon surfaces, such as highly ordered pyrolytic graphite (HOPG) and carbon nanotubes(CNTs). As phen-dione and Ru(bpy)2(phen-dione)2+ were subjected to cathodic reduction, phen-diol and Ru(bpy)2(phen-diol)2+ could be formed, making the products possible to be attached to the boronates grafted to the carbon surfaces from APBA. STM, electrochemical impedance (EIS) and cyclic voltammetry (CV) support the results. The magnetic-mode AFM, in addition , showed that the resultant CNTs exhibited photomagnetism as exposed the 473- nm light. The photomagnetism is highly reproducible. The created carbon surfaces are useful in spintronics.
