Description

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 is shown to depend 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

Abstract (Russian)

Исследованы электрохимическое поведение и спектральные свойства серии симметричных 2,3,9,10,16,17,23,24,2',3',9',10',16',17',23',24'-гексадекаалкилзамещенных дифталоцианиновых комплексов лантанидов (R8Pc)2Ln (R = Н, Me, Et, Bun; Ln = Eu, Dy, Lu). Установлены закономерности изменения изученных параметров в зависимости от природы лантанида и заместителей во фталоцианиновых макролигандах. Показано, что положение интервалентной полосы поглощения комплексов в ближней ИК-области зависит не только от эффективного расстояния между макролигандами, но и от электронного влияния заместителей. Обнаружены корреляции между электрохимическими и спектральными свойствами комплексов
