| Abstract: | The electrochemical behavior and spectral properties of a series of symmetrical 2,3,9,10,16,17,23,24,2’,3’,9’, 10’,16’,17’,23’,24’-hexadecaalkyl-substituted lanthanide complexes (R8Pc)2Ln (R = H, Me, Et, Bun; Ln = Eu, Dy, Lu) were studied. Regularities of changing the parameters under study were established, depending on the nature of lanthanide and substituents in the phthalocyanine macroligands. The position of the intervalence band of the complexes in the near-IR region depends on the effective distance between the macroligands and also on the electronic effect of the substituents. Correlations between the electrochemical and spectral properties of the complexes were found.__________Published in Russian in Izvestiya Akademii Nauk.
