Encapsulation and characterization of Co(AC)(2)-5,10,15,20-tetra-p-hydroxyphenylporphyrin in Si-MCM-41 by the method of ship-in-bottle

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, therma l stabilities of the complex before and after encapsulation, coordination s tate between Co(AC)(2) and 5,10,15,20-tetra-p-hydrdxyphenylporphyrin in Si- MCM-41 and the hydrothermal stability of the complex in Si-MCM-41 were stud ied by the methods of ICP, DTA, XRD, EPR, XPS and UV-Vis spectra. It indica ted that the Co(AC)2 was coordinated with 5,10,15,20-tetra-p-hydroxyphenylp orphyrin completely in Si-MCM-41. The hydrothermal and the thermal stabilit y of the complex after being encapsulated are higher than that of the pure complex.
