| Popis: | An in situ spectroelectrochemical study of the oxidation of the μ-oxosilicon phthalocyanine dimer [(SiPc)2O][OSiHx3]2 utilizing cyclic voltammetry, electron spin resonance spectroscopy, and visible–near infrared spectroscopy has been carried out. The results of this study show that oxidation of the dimer yields the paramagnetic radical dimer [(SiPc)2O][OSiHx3]2 + and then the diamagnetic dimer [(SiPc)2O][OSiHx3]22+. The study shows that the rings of [(SiPc)2O][OSiHx3]22+ are antiferromagnetically coupled. |
