The Chlorophyll is composed of a heterocyclic ring, known as a porphyrin or chlorin (reduced form) with a Magnesium atom at its center and a long hydrocarbon (phytol) chain. Chlorophyll is an essential element of the photosynthesis and is present in plants, algae, and cyanobacteria.  Porphyrin related compounds have attracted attention for its potential use in the energy, catalyst, medicine, and pigments industry. The substitution of magnesium by different transition metals of chlorophyll type a and b was studied. Analysis of the change in the complex will indicate a change in its property and the effect it may have on different reactions. The purpose of this research is to determine the changes of chlorophyll when the central metal ion is exchanged for a different metal.
