我們以Ru(bpy)2Cl2和NH2-phen合成Ru(bpy)2(NH2-phen)2+，再以偶氮還原修飾法將此錯合物鍵結於多壁奈米碳管和HOPG表面，成為Ru@CNT、Ru@HOPG。經由磁性分析，我們發現在室溫下2,2’-二吡啶-5-胺基菲繞啉釕化合物、Ru@CNT與Ru@HOPG受到473-nm雷射光照射時，會顯現光磁性。我們進而以之製備具有光磁轉換功能的磁性原子力顯微術(MFM)掃瞄探針，以分析磁性物質表面。有鑒於市售MFM探針易被氧化，不易保存，於磁性物質分析上存在困擾，故若以2,2’-二吡啶-5-胺基菲繞啉釕化合物製備MFM探針，將可有效避免除此一困擾。

We synthesized Ru(bpy)2(NH2-phen)2+ by reacting Ru(bpy)2Cl2 with 1,10-phenanthrolin-5-amine (NH2-phen), and then attached the resulting product on multi-walled carbon nanotube and highly oriented pyrolytic graphite (HOPG) through diazotization/denitrogenation processes. We found that Ru(bpy)2(NH2-phen)2+ and the resulting Ru@CNT and Ru@HOPG exhibited magnetism as exposed to the 473-nm light at room temperature. In view of the fact that most metal-coated magnetic-mode AFM (MFM) tips are prone to oxidation in the air, we then devoted efforts to modifying Ru(bpy)2(NH2-phen)2+ on commercial silicon-based tips to fabricate photomagnetic AFM tips. The resultant tips show application potential in MFM imaging.
