dc.description.abstract | 有鑒於亞硼酸可與羥基化合物進行環合反應產生亞硼酸酯,本論文探討以偶氮還原修飾法先將3-氨基苯亞硼酸(簡稱APBA)修飾於熱解石墨(簡稱HOPG)或奈米碳管表面,再藉由電化學或化學還原反應將2,2'-二吡啶-5,6-二羰基菲囉啉釕錯合物(簡稱Ru(bpy)2(phen-dione)2+)還原成2,2'-二吡啶-5,6-二羥基菲囉啉釕錯合物,使之與APBA進行環合反應,進而固定於這些碳質表面。 掃瞄式穿隧顯微術(簡稱STM)分析顯示:HOPG表面的粗糙度在修飾APBA後會由0.259 nm 增高至0.397 nm。若再經Ru(bpy)2(phen-dione)2+修飾,則會再增高至0.783 nm,其差值約為單層APBA與Ru(bpy)2(phen-dione)2+吸附。電化學交流阻抗與循環伏安法均證實此一現象。磁性模組AFM顯微術證實所修飾的奈米碳管受473-nm雷射光照射下時會顯現光磁性。由於該光磁性具有再現性,以亞硼酸酯環合反應所製備的碳質表面極具室溫光磁轉換應用潛力。 | zh_TW |
dc.description.abstract | 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. | en_US |
