Аннотация:Efficient direct synthesis of new monomeric and stable J-type dimeric species of 2-hydroxy-9(10),16(17),23(24)-tri-tert-butylphthalocyaninato aluminum with high yields, including preparation of the corresponding dimeric free-base ligand at ambient conditions, has been developed. The compounds were characterized by the UV–Vis spectroscopy as well as MALDI-TOF mass-spectrometry and thermogravimetry data. The in-depth study of the produced aluminum complexes by 1D and 2D 1H NMR techniques was carried out owing to elaboration of disaggregating CD3ONa/CD3OD system featuring formation of phthalocyanine phenolate anions. Surface morphology of thin films formed by the complexes was studied by scanning (FE-SEM) and atomic force (AFM) microscopies. According to the AFM data, the films are characterized by granular structure, while the grain diameter accounts for 50 and 100 nm for the monomeric and dimeric complex, respectively.
