当铂、铜和锌酞菁真空蒸发到白云母的解理面上时，在较低的基板温度下会发生单向取向。在较高温度范围内，Zn-酞菁具有双向取向，而Pt-和Cu-酞菁则呈现三向取向。高分辨率电子衍射图是明确的纤维图，显示所有三种化合物彼此都表现出明显的同构性，并且锌酞菁和铜酞菁以其二晶型的亚稳态形式存在。在发现的与 Pt 衍生物同构的基础上，讨论了亚稳态形式的一般晶体结构。蒸发膜由层状晶体条组成，纤维图显示所有三种化合物都呈现至少两种晶格取向，而单个条的纵向晶轴始终平行于它们的 b 轴。至于蒸发膜与基底的相对取向，t...
When Pt‐, Cu‐, and Zn‐phthalocyanines are vacuum‐evaporated onto cleavage faces of muscovite, single‐directional orientation occurs at lower substrate temperature. At higher temperature ranges, Zn‐phthalocyanine has a double‐directional orientation while Pt‐ and Cu‐phthalocyanines show triple‐directional ones. High‐resolution electron diffraction patterns, which were well‐defined fiber diagrams, revealed that all three compounds showed conspicuous isomorphism with one another, and Zn‐ and Cu‐phthalocyanines occurred in the metastable forms of their dimorphs. General crystal structures of metastable forms are discussed on the basis of the found isomorphism with Pt‐derivative.Evaporated films were composed of lamellar crystal strips, and the fiber diagrams showed that at least two kinds of lattice orientations were assumed by all three compounds, while the longitudinal crystal axis of individual strips always ran parallel to their b axes.As to relative orientation of the evaporated films to the substrate, t...
