Description

General description

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
