Abstract The supramolecular organization of the A3B-type phthalocyanine holmium complex (A3B–Ho) was investigated in floating layers at the air–water interface and in Langmuir-Schaefer thin films at the air–solid interface. The floating layers formed under different experimental conditions on the water subphase using the Langmuir technique. They were studied by Brewster angle microscopy, grazing incidence X-ray diffraction and X-ray reflectometry. It was established that molecules of A3B–Ho form stable ordered floating monolayer on the water surface. Experimental conditions required for this monolayer formation were determined as following: the initial degree of coating of the water surface was 18%, the compression rate of barriers was 6 cm2/min and the surface pressure was 0.4 mN/m. Under these conditions a stable crystalline monolayer structure was obtained with an area per one molecule 3.9 nm2. It has a two-dimensional face-on packing with the intralayer period of 2.06 nm. The Langmuir-Schaefer thin film was obtained on the basis of the above mentioned monomolecular floating layer. The film possesses a single two-dimensional structure with the packing of the molecules parralel to the substrate surface that was revealed by electron diffraction. The lattice parameters of the monomolecular film were a = 1.65 nm, b = 1.92 nm, γ1 = 75. It was shown that the film preserves the structure of the floating monolayer.

介晶混合取代酞菁钬配合物的浮层和薄膜

摘要 在空气-水界面的漂浮层和空气-固体界面的 Langmuir-Schaefer 薄膜中研究了 A3B 型酞菁钬配合物 (A3B-Ho) 的超分子组织。漂浮层在不同实验条件下使用朗缪尔技术在水亚相上形成。通过布鲁斯特角显微镜、掠入射 X 射线衍射和 X 射线反射法对它们进行了研究。已确定 A3B-Ho 分子在水面上形成稳定有序的漂浮单层。该单层形成所需的实验条件确定如下：水面的初始涂层度为18%，屏障的压缩率为6 cm2/min，表面压力为0.4 mN/m。在这些条件下，获得稳定的单层晶体结构，每个分子的面积为 3.9 nm2。它具有二维正面填料，层内周期为 2.06 nm。Langmuir-Schaefer薄膜是在上述单分子浮层的基础上得到的。该薄膜具有单一的二维结构，分子的堆积与基板表面平行，电子衍射揭示了这一点。单分子膜的晶格参数为a = 1.65 nm, b = 1.92 nm, γ1 = 75。表明该膜保留了浮动单层的结构。Langmuir-Schaefer薄膜是在上述单分子浮层的基础上得到的。该薄膜具有单一的二维结构，分子的堆积与基板表面平行，电子衍射揭示了这一点。单分子膜的晶格参数为a = 1.65 nm, b = 1.92 nm, γ1 = 75。表明该膜保留了浮动单层的结构。Langmuir-Schaefer薄膜是在上述单分子浮层的基础上得到的。该薄膜具有单一的二维结构，分子的堆积与基板表面平行，电子衍射揭示了这一点。单分子膜的晶格参数为a = 1.65 nm, b = 1.92 nm, γ1 = 75。表明该膜保留了浮动单层的结构。
