| 内容記述 | Scanning tunneling microscopy (STM) has been a powerful tool in surface science. STM, however, often lacks chemical selectivity. In this laboratory, it has been demonstrated that the use of molecular tips allows STM to attain the chemical selectivity. The chemical selectivity arises from the facilitation of electron tunneling by chemical interactions between tip molecules and particular chemical species of sample molecules. The available interactions reported so far include hydrogen bond and metal-coordination interactions. In the present study, I showed facilitation of electron tunneling through charge-transfer interaction, which allows us to locate electroactive moieties and to construct a novel intermolecular junction for testing molecular-scale electronic devices. In addition, it was demonstrated that carboxy-terminated single-walled carbon nanotube (SWNT) tips enable high resolution and chemically selective observation. Finally, it was shown that the selective observation of oxygen-containing functional groups can be tailored by controlling the extent of the hydrogen bond acidity or basicity of tip molecules. | |||||
