Synthesis and Properties of Metal Complexes of Ether-bonded Porphyrin–Chlorin Dimer

A number of metal complexes of dimeric porphyrin–chlorin ether have been prepared; bis-zinc porphyrin–chlorin was shown to undergo photooxidation of the chlorin moiety, bis-zinc porphyrin–chlorin and porphyrin–porphyrin were also shown to form addition products with one oxygen molecule.
