Porphine or porphin is an organic compound of empirical formula C20H14N4. It is heterocyclic and aromatic. The molecule is a flat macrocycle, consisting of four pyrrole-like rings joined by four methine bridges, which makes it the simplest of the tetrapyrroles. [1]
The nonpolar tetrapyrrolic ring structure of porphine means it is poorly soluble in most organic solvents and hardly water soluble. [2] As a result, porphine is mostly of theoretical interest. It has been detected in GC-MS of certain fractions of Piper betle. [3]
Substituted derivatives of porphine are called porphyrins. Many porphyrins are found in nature with the dominant example being protoporphyrin IX. [4] Many synthetic porphyrins are also known, including octaethylporphyrin [5] and tetraphenylporphyrin. [6]
