Incorporation of an asymmetry gadolinium porphyrin into mesoporous SBA-15 and the study of luminescence property

The incorporation of an asymmetry gadolinium porphyrin into the mesoporous molecular sieves SBA-15 by reactions of the surface OH group with an F and OH group of the porphyrin. The resultant material was confirmed that the channels of SBA-15 have been filled with porphyrins by XRD, TEM, solid UV/Vis, nitrogen adsorption, leaving the mesopores unaffected. Luminescent properties were studied by solid fluorescence emission and excitation spectra. Results indicate that the luminescence intensity of SBA-15/porphyrin is stronger than the pure porphyrin. We also provided the FTIR results and study the links between silica wall and gadolinium porphyrin after incorporation porphyrin into SBA-15.
