• Phthalocyanine
• Electronic absorption
• Magnetic circular dichroism
• Aromaticity

Unexpected formation of seco-tribenzoporphyrazines from nickel- or palladium-template macrocyclization reaction of 1,3-diiminoisoindoline as a sole starting material has opened a novel access to this class of molecules. Seco-tribenzoporphyrazines exhibit strongly-split Q band absorption, basically typical of tetraazachlorin-like electronic structures, which are discussed in detail based on UV-Vis absorption and magnetic circular dichroism spectroscopies and theoretical calculations.
