5,10,15,20-TETRA(4-PYRIDYL)-21H,23H-PORPHINE

Purple to dark purple solid

5,10,15,20-Tetra(4-pyridyl)-21H,23H-porphine is used in the making of coordination catalysts.

5,10,15,20-tetra-4-pyridyl-21H,23H-porphine (H₂TPyP)?can react with [Re₆(μ₃-Se)₈(Pet₃)₅(NCMe]²⁺ and 2,4,6-tri-4-pyridyl-1,3,5-triazine to form tri- and tetra complexes. 1 Trace amounts of nitroaromatic explosives can be detected by porphyrin functionalized graphene. It behaves as a sensitive amperometric sensor. 2

Purify it by chromatography on alumina (neutral, Grade I), with CHCl3/MeOH (80:20) followed by recrystallisation from CH2Cl2/MeOH [Yamashita et al. J Phys Chem 91 3055 1987]. [Kalyanasundaram Inorg Chem 23 2453 1984, Okuno et al. Synthesis 537 1980.]
