Thermal splitting of bis-Cu(II) octaphyrin (1.1.1.1.1.1.1.1) into two Cu(II) porphyrins

The thermal splitting reaction of bis-Cu(II) complex of octaphyrin (1.1.1.1.1.1.1.1) in two Cu(II) porphyrins is reported. The conclusion states that this Cu(II) gives rise to the facile splitting reaction triggered by increased distortion in the bis-metal complex, which provides a rare example of molecular mitosis for expanded porphyrins.
