Synthesis of a pyridine-fused porphyrinoid: oxopyridochlorin.
The treatment of 3,5-dibenzoylporphyrins with ammonium acetate provided novel oxopyridochlorins as the first examples of pyridine-fused porphyrinoids, which displayed absorption bands reaching into the near IR region and an ability to sensitize singlet oxygen effectively.
