Abstract

Abstract: Co(AC)₂-5,10,15,20-tetra-p-hydroxyphenylporphyrin was encapsulated in Si-MCM-41 by the method of ship in bottle. The content of the complex, thermal stabilities of the complex before and after encapsulation, coordination state between Co(AC)₂ and 5,10,15,20-tetra-p-hydroxyphenylporphyrin in Si-MCM-41 and the hydrothermal stability of the complex in Si-MCM-41 were studied by the methods of ICP, DTA, XRD, EPR, XPSand UV-Vis spectra. It indicated that the Co(AC)₂ was coordinated with 5,10,15,20-tetra-p-hydroxyphenylporphyrin completely in Si-MCM-41. The hydrothermal and the thermal stability of the complex after being encapsulated are higher than that of the pure complex.

Key words: Si-MCM₄₁, Hydrothermal stability, Encapsulation
