固载化金属酞菁(MPc)催化性能的研究——Ⅱ.MPc通过配位连接在硅胶上及其对O_2的活化作用

STUDY ON CATALYTIC ACTIVITY OF SUPPORTED METAL PHTHALOCYANINE(MPc)——Ⅱ. MPc LINKED TO THE SURFACE OF SILICA GEL AND ITS ACTIVATION ACTION ON OXYGEN

用有机合成的方法在硅胶表面连接上可与MPc配位的有机基团——(CH_2)_3N(C_2H_5)_2,MPc与之配位从而固载在硅胶上。UV-Vis漫反射光谱表明硅胶表面存在MPc。用ESR研究固载化MPc与O_2的作用,证明固载化CoPc、FePc可以与O_2作用产生O_2^-,CuPc则不能。

The MPcs (M=Fe^(2+), Co^(2+), Cu^(2+); Pc=phthalocyanine ) were coordinated with —(CH_2)_3N(C_2H_5)_2 group of SiO_2 ,which had been linked with above group through organic synthesis.The UV-Vis diffuse reflection spectra revealed this supporting. ESR result indicated that only the supported CoPe and FePc were capable of reacting with O_2 producing O_2^-.
