title: Superazaporphyrins: meso-pentaazapentaphyrins and one of their low-symmetry derivatives.
abstract: Supersized: Three pentaazapentaphyrin derivatives, that is, the superazaporphyrins (SAzPs), as well as a superphthalocyanine (SPc) and a mixed low-symmetry derivative have been prepared and characterized. Decaaryl SAzPs have a distorted (4n+2) π structure and show the Q bands at about λ=840-880 nm. These compounds are relatively air stable.
