Dendritic Iron(III) Carbazole Complexes: Structural, Optical, and Magnetic Characteristics.

ABSTRACT: This paper focuses on the synthesis, structural characterization, and study of the optical, magnetic, and thermal properties of novel architectures combining metal ions as magnetoactive centers and photoactive blocks formed by carbazole units. For this purpose, a series of azomethine complexes of the composition [Fe(L)2]X (L = 3,6-bis[(3',6'-di-tert-butyl-9-carbazol)-9-carbazol]benzoyloxy-4-salicylidene-N'-ethyl-N-ethylenediamine, X = NO3-, Cl-, PF6-) were synthesized by the reaction of metal salts with Schiff bases in a mixture of solvents. The UV-Vis absorption properties were studied in dichloromethane and rationalized via time-dependent density functional theory (DFT) calculations. Upon excitation at 350 nm, the compounds exhibited an intense dual fluorescence with two emission bands c
