Abstract
We describe an alternative methodology for the synthesis of β-pyrazine-fused diporphyrins in high yields from 2-amino-5,10,15,20-tetraphenylporphyrin nickel(II) derivatives by using p-dodecylbenzenesulfonic acid as an efficient Brønsted acid catalyst in 1,4-dioxane at 90 °C. The structural characterization, material morphology and electronic properties of the products are reported.
