| Abstract: | Uncharged water‐soluble porphyrins were prepared by reaction between tetrakis(p‐hydroxyphenyl)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 2000–21 000 Da. Structural characterization of these star polymers was performed by means of gel permeation chromatography, NMR spectroscopy, and MALDI‐TOF analysis. |
