利用扫描隧道显微镜研究了碘代十八烷与取代酞菁在石墨表面的组装行为。通过改变连接于酞菁环上的取代基,可以使之与碘代十八烷在石墨表面形成均匀组装或者相分离结构。研究结果表明,酞菁分子间相互作用力的强弱是形成何种组装结构的决定因素。
The assembly behavior of iodine octadecane and substituted phthalocyanine on graphite surface was investigated by scanning tunneling microscope. By changing the substituents attached to the phthalocyanine ring, octadecyl iodide can be uniformly assembled or phase-separated from the graphite surface. The results show that the strength of the interaction between the phthalocyanine molecules is the decisive factor in the formation of the assembly structure.
