Morphological Engineering of Porphyrin Porous Organic Polymers

Porphyrin Porous Organic Polymers (POPs) have been proved to have outstanding photocatalytic activity and can be used in several fields. Our research aims to the morphological engineering of porphyrin POPs materials. Using SiO2 as template materials, the morphological structures of Porphyrin POPs could be well controlled in the nanoscale. We modified the silica sphere with amino group and aldehyde group and then used the typical Stöber method to synthesize the porphyrin structure. The samples were well characterized by nitrogen adsorption, Power X-Ray Diffraction (PXRD), Transmission Electron Microscopy (TEM) and Fourier-Transform Infrared Spectroscopy (FTIR) spectra and the analysis results showed that the morphorlogy and size of the sphere Porphyrin POPs were well controlled. After etch, we get a shell structure made by polyporphyrin POPs in nanoscale. The shell structure of the porphyrin POPs paving the way for the applications as treatment platform in vivo.
