Abstract:
Uncharged water-soluble porphyrins were prepared by reaction between tetrakis(p-hydroxy-phenyl)porphyrin and chlorinated poly(ethylene glycol)methyl ethers of different molecular weights. Water-solubility was achieved by binding four poly(ethylene glycol) branches to a porphyrin core to give star polymers with molecular weights in the range 2000 - 21000 Da. Structural characterization of these star polymers was performed by means of gel permeation chromatography, NMR spectroscopy and MALDI-TOF analysis.
