In the first year of the term of this project, we found that symmetry lowered metallophthalocyanine, 2,3 : 12,13-dibenzophthalocyaninato-Zn (II) (ZnDBPc) shows high optical non-linearity when this novel material is deposited on a sapphire base plate under ultra-low pressure and appropriate temperature. When titanylphthalocyanine (TiOPc) was deposited on a thin film of ZnDBPc, the nonlinearity of this double layred film was improved to ten times more, and the alignment of molecules on the film was uniform over the large area of 10mm x 13mm. On the other hand, we clatified spectroscopic properties of symmetry-lowerd phthalocyanines in terms of the group theory and first-order perturbation treatment.In the second year of the term, we investigated the reason why ZnDBPc molecules are oriented uniformly over the sapphire plate using X-ray diffraction, scanning electron microscope, ultraviolet photoelectron spectra, and so on. As the results, we have found that the crystal growth of ZnDBPc molecule is dominated by interaction between molecules on contrary to a common expectation such that the growth is dominated by interactions between molecules and the base plate.

在本项目的第一年，我们发现对称性降低的金属酞菁化合物2，3：12，13-二苯并酞菁合锌（ZnDBPc）在超低压和适当温度下沉积在蓝宝石基板上时显示出高的光学非线性。将酞菁钛（TiOPc）沉积在ZnDBPc薄膜上，双层薄膜的非线性系数提高了10倍以上，并且在10 mm × 13 mm的大面积上分子排列均匀。另一方面，我们从群论和一级微扰的角度对ZnDBPc的光谱性质进行了分类，在学期的第二年，我们利用X射线衍射、扫描电子显微镜、紫外光电子能谱等方法研究了ZnDBPc分子在蓝宝石片上均匀取向的原因，结果表明，我们已经发现ZnDBPc分子的晶体生长由分子之间的相互作用控制，这与通常的预期相反，即生长由分子和基板之间的相互作用控制。
