利用低能电子衍射和扫描隧道显微镜研究了铁酞菁在Ag（111）上的单层外延生长。在生长过程中，分子层经历了很少的结构相变，并发现了各种斜或矩形单元胞的超晶格。我们发现不同中心金属原子的酞菁和酞菁衍生物在不同分子覆盖范围下形成的最稳定的分子超结构的形态。
An experimental investigation of the epitaxial growth of iron-phthalocyanines on Ag(111) has been conducted in the monolayer range by low-energy electron diffraction and scanning tunneling microscopy. During the growth, the molecular overlayer undergoes few structural phase transitions, and various superlattices with oblique or rectangular unit cells have been identified. We show that the morphologies of the most stable molecular superstructures formed for different molecular coverage are adopted by various phthalocyanines with different central metal atom and phthalocyanine derivatives.
