二元化合物在石墨表面的分子自组装

Molecular Self-assembly of Binary Compounds on the Surface of Graphite

采用接触角测试及扫描隧道显微镜(STM)分析测试了二元化合物[C8-TPP-(ip)Ru(phen)2](C lO4)2在高定向裂解石墨衬底上形成的自组装膜。接触角测试结果显示自组装膜具有较强的疏水性。STM观测结果发现[C8-TPP-(ip)Ru(phen)2](C lO4)2在石墨表面形成两种不同畴界的自组装形式,并初步分析了其形成的原因。

Based on the contact angle testing and scanning tunneling microscopy(STM),the article analyzed and tested the self-assembled monolayer of binary compounds[C8-TPP-(ip)Ru(phen)2](ClO4)2,which was formed on the highly oriented graphite substrate(HOPG).The result of the contact angle testing showed that the self-assembled monolayer had stronger hydrophobic nature.The observational result of STM indicated [C8-TPP-(ip)Ru(phen)2](ClO4)2 could form self-assembly in two different domain boundaries on the surface of graphite,and initially explained the forming reasons.
