Abstract

   The synthesis and characterization of a new functionalized porphyrin (Mg8OHPor) with eight directly appended phenolic hydroxyl groups are described. The synthesis of this porphyrin was carried out in three stages: first synthesizing H28OMePor, then converting it to H28OHPor, and finally complex formation into Mg8OHPor. The formation of porphyrins was confirmed by 13C-NMR and ESI-MS measurement. Additionally, ESI-MS spectra of Mg8OHPor containing polar organic molecules also indicated the formation of an organic molecule–porphyrin complex coordinated from the phenolic hydroxyl groups and the metal. The design strategy of the porphyrin helped to extend the development of a porphyrin-based cancer photodynamic therapy (PDT).
