    • Protonation-Induced Hyperporphyrin Spectra of meso-Aminophenylcorroles 

      Thomassen, Ivar K.; Ghosh, Abhik (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-06)
      UV–vis spectrophotometric titrations have been carried out on <i>meso</i>-tris(<i>o/m/p</i>-aminophenyl)corrole (H<sub>3</sub>[<i>o/m/p</i>-TAPC]) and meso-triphenylcorrole (H<sub>3</sub>[TPC]) in dimethyl sulfoxide with methanesulfonic acid (MSA). Monoprotonation was found to result in hyperporphyrin spectra characterized by new, red-shifted, and intense Q bands. The effect was particularly dramatic ...

    • Simple, Axial Ligand-Mediated Route to Water-Soluble Iridium Corroles 

      Thomassen, Ivar K.; Rasmussen, Daniel; Einrem, Rune F.; Ghosh, Abhik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-15)
      The synthesis and purification of water-soluble porphyrin-type compounds for photodynamic therapy and other medical applications is often a tedious exercise. Here, we have investigated the simple stratagem of adding a water-soluble axial ligand to the standard protocol for iridium insertion into simple meso-triarylcorroles. Early results showed that six-coordinate Ir[TpXPC](dna)2 derivatives, in ...
