Background: Co(II) meso-Tetraphenylporphine (contains 1-3% chlorin) is a synthetic porphyrin specialty chemical manufactured by Frontier Specialty Chemicals. Co(II) meso-Tetraphenylporphine was investigated as an electrocatalysis of the reduction of CO2.1 Co(II) meso-Tetraphenylporphine was immobilized on a conductive polymer film electrode as a catalytic site.2 Co(II) meso-Tetraphenylporphine was found to be active as a photo oxygenation catalyst and gives different products then those obtained with Rose Bengal when applied to the photo oxygenation of indene derivatives.3 Co(II) meso-Tetraphenylporphine was used to functionalize graphitic carbon nitride to produce an improve hydrogen evolution photo catalyst.4 Co(II) meso-Tetraphenylporphine was used in a process to functionalize carbon nano tubes by absorption and pyrolysis to produce a Co-N-C catalysis for oxygen electrocatalysis.5  Co(II) meso-Tetraphenylporphine was used to produce a polymeric ion-selective electrode of the iodide ion.6
