Abstract:

Time-dependent density functional theory (TDDFT) calculations using the B3LYP method were used to investigate the effect of β-substituents on the electronic absorption spectra of a series of manganese(Ⅴ)-oxo corrole complexes. The geometries, frontier molecular orbitals, and energies of the complexes were analyzed. The calculated results indicate that the steric effect of the β-substituents is the factor controlling the red-shift of the Soret bands and Q bands in these complexes. The sterically hindered β-substituents cause twisting of the corrole ring structure, which leads to reduced orbital energy gaps and a red-shift of the Soret bands and Q bands.

Key words: Manganese(Ⅴ)-oxo corrole, Electronic absorption spectrum, TDDFT, Substituent
