Preparation of SiO_2-ligated Metallo-phthalocyanine (MPc) and it's Role in the Activation of Dioxygen

The metal phthalocyanines (MPc, M=Fe, Co, Cu) were supported on the surFace of silica gel by chemical linking.They could not be washed out with organic solvents such as Py.UV-Vis diFFuse reFlectance spectra indicated that MPc's were supported on silica gel.ESR result showed that the supported CoPc and FePc could react with O2 to produce O2, but the supported CuPc could not.国家自然科学基
