Chlorin

Structures comparing porphin, chlorin, bacteriochlorin, and isobacteriochlorin.  Note relocation of C=C double bond between the two bacteriochlorin isomers. There are two π electrons (symbolized by π e−) for every double bond in the macrocycle.

In organic chemistry, a chlorin is a large heterocyclic aromatic ring consisting, at the core, of three pyrroles and one pyrroline coupled through four =CH- linkages. Unlike porphin, the central aromatic ring structure of porphyrins, a chlorin is therefore largely aromatic but not aromatic through the entire circumference of the ring.
