Solar conversion : Zinc hydroxyisoporphyrin ( 2 ), under sunlight and argon, is reduced back to zinc meso ‐tetraphenylporphyrin ( 1 ), but stays stable in oxygen in the absence of light. This behavior is in contrast to its iron analogue and stresses the redox role of iron in heme degradation. Compound 2 also responds to chlorophyll‐type degradation ( 3 ) under sunlight and oxygen.
