4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Attachment of the ligand to the metal may be through a single atom, in which case it is called a monodentate ligand, or through two or more atoms, in which case it is called a didentate or polydentate ligand. The actual catalysts are metal complexes that are prepared from ligands and appropriate metal precursors.Reference of 57412-08-5

Synthesis and nuclease activity of some porphyrin-acridone hybrid molecules was written by Mehta, Goverdhan;Sambaiah, Thota;Maiya, Bhaskar G.;Sirish, Mallena;Chatterjee, Dipankar.

Porphyrin-acridone hybrids I (n = 2-6) were prepared from 5-(4-hydroxyphenyl)-10,15,20-tris(p-tolyl)porphyrin by haloalkylation and reaction with acridone. I showed highly efficient energy transfer and nicking of supercoiled pBR322 DNA. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Reference of 57412-08-5).
