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-solu-bility 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. Struc-tural characterization of these star polymers was per-formed by means of gel permeation chromatography, NMR spectroscopy, and MALDI-TOF analysis

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-solu-bility 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. Struc-tural characterization of these star polymers was per-formed by means of gel permeation chromatography, NMR spectroscopy, and MALDI-TOF analysisFile in questo prodotto:
