通过测定可见光谱的变化,在广泛范围内研究了溶液中酞菁铁(Ⅱ)和多种给电子配体之间的轴向配位作用。发现轴向配位作用对Q_(o-o)带的影响不如对吸收带Ⅱ的那么显著,后者在配体的σ-给予性的作用下可以显现或发生红移,其原因被认为是在铁离子中的dπ轨道和酞菁环的eg(π~(?))轨道之间发生电荷转移eg(dπ)(M)→eg(π~(?))Pc所致。对含同一配位原子(S、O、N)来说,在各自的Q_(o-o)和Ⅱ带的能量之间有一线性关系,而斜率则可能和配位原子的电负性有关。
By measuring the change of the visible spectrum, the axial coordination between iron phthalocyanine (Ⅱ) and various donor ligands in solution has been studied in a wide range. It was found that the effect of axial coordination on the Qo (oo) band was not as pronounced as that of the absorption band II, the latter being able to show or redshift under the sigma- Eg (dπ) (M) → eg (π ~ (?)) Pc between the dπ orbit in the ion and the eg (π ~ (?)) Orbit of the phthalocyanine ring. For the same coordination atoms (S, O, N), there is a linear relationship between the energies of the respective Q_ (o-o) and II bands, and the slope may be related to the electronegativity of the coordination atoms.
