Based on 4,4'-[1,3/4-phenilenebis(oxy)]phthalodinitriles, the mixture of phthalocyaninates of various structures with rare-earth metals were obtained by template fusion method minimizing the side polymerization processes. Target monophthalocyaninates were isolated from the reaction mixture and purified using column and then gel permeation chromatography. The compounds were characterized by NMR, IR spectroscopy, mass spectrometry, and elemental analysis. The spectral properties were studied and the aggregation behavior of the synthesized Er, Yb, and Lu phthalocyaninates in chloroform, acetone, and tetrahydrofuran was determined. It has been shown that lutetium complexes with 3,4-dicyanophenoxyphenoxy ligands are the least stable and least resistant to aggregation in solution, while erbium and ytterbium phthalocyaninates proved to be stable in all studied media. The quantum yields and fluorescence lifetimes of the complexes in chloroform and tetrahydrofuran were calculated.
基于 4,4'-[1,3/4-亚苯基双（氧）]邻苯二甲腈，通过模板熔融法获得了具有各种结构的镧系金属酞菁酸盐混合物，从而最小化了副聚合过程。从反应混合物中分离出目标单酞菁酸盐，并使用柱色谱和凝胶渗透色谱进行纯化。通过 NMR、IR 光谱、质谱和元素分析对化合物进行了表征。研究了光谱性质，并确定了合成的 Er、Yb 和 Lu 酞菁酸盐在氯仿、丙酮和四氢呋喃中的聚集行为。结果表明，具有 3,4-二氰基苯氧基苯氧基配体的镥配合物在溶液中最不稳定且最易聚集，而铒和镱酞菁酸盐在所有研究的介质中均稳定。计算了配合物在氯仿和四氢呋喃中的量子产率和荧光寿命。
