Correlations between electrochemical and spectral properties
of alkyl-substituted diphthalocyanine lanthanide complexes
I. V. Zhukov,(a)* V. E. Pushkarev,(a) L. G. Tomilova,(b) and N. S. Zefirov(a)
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.
