Zn(II)phthalocyanine molecules (ZnPc) were thermally deposited on a rutile TiO(011) surface and on Zn(II)-tetraphenylporphyrin (ZnTPP) wetting layers at room temperature and after elevated temperature thermal processing. The molecular homo- and heterostructures were characterized by high-resolution scanning tunneling microscopy (STM) at room temperature and their geometrical arrangement and degree of ordering are compared with the previously studied copper phthalocyanine (CuPc) and ZnTPP heterostructures. It was found that the central metal atom may play some role in ordering and growth of phthalocyanine/ZnTPP heterostructures, causing differences in stability of upright standing ZnPc versus CuPc molecular chains at given thermal annealing conditions.
在室温下以及经过高温热处理后，将锌（II）酞菁分子（ZnPc）热沉积在金红石TiO(011)表面和锌（II）-四苯基卟啉（ZnTPP）润湿层上。通过室温下的高分辨率扫描隧道显微镜（STM）对分子均相和异质结构进行了表征，并将其几何排列和有序程度与之前研究的铜酞菁（CuPc）和ZnTPP异质结构进行了比较。研究发现，中心金属原子可能在酞菁/ZnTPP异质结构的有序排列和生长中发挥一定作用，导致在给定的热退火条件下，直立的ZnPc分子链与CuPc分子链的稳定性存在差异。
