【摘要】 本文制备了石英基片表面的蒽甲基胺自组装膜,荧光光谱测试结果表明该膜在450￣500nm波段产生较强的excimer发射峰,这应与成膜分子的有序排列加强了蒽环间的相互作用有关。利用该自组装膜通过固/液界面相互作用实现了ZnⅡ和AgⅠ的荧光识别。不同金属离子与膜分子结合对蒽环排列产生的不同影响是实现识别的主要机制。更多还原

【Abstract】 A self-assembled monolayer of aminomethyl anthracene on quartz plate was prepared. Fluorescent spectroscopic study demonstrated a strong excimer emission band between 450 nm and 500 nm, suggesting the effective-interaction between anthracene planes due to the high order of molecules in the monolyer. The self-assembled monolayer could recognize ZnⅡ and AgⅠ by fluorescence determination after the interfacial solid/liquid molecular interaction. The variable-interaction between anthracene planes induced by different metal ions may be the origin for the recognition.更多还原
