A series of mono-alkylcarboxylic acid derivatives of tetraphenylporphyrin have been prepared All the porphyrins were completely characterized by use of mass, ¹H NMR, UV-visible, and fluorescence spectroscopy. Exptl. log P were determined by use of reversed-phase thin-layer chromatog. with use of log P_Rekker. These porphyrins are potential photosensitizers in photodynamic therapy. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Electric Literature of C47H36N4O).

4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. A ligand is an ion or molecule, which donates a pair of electrons to the central metal atom or ion to form a coordination complex. The ability of ligands to engender a variety of useful properties of organometallic complexes is the major enabling force for the discovery of new catalytic reactions, activation of small molecules, dramatically enhanced reactivity.Electric Literature of C47H36N4O

Templated self-assembly of porphyrin cages was written by Elemans, Johannes A. A. W.;Slagt, Vincent F.;Rowan, Alan E.;Nolte, Roeland J. M.. And the article was included in Israel Journal of Chemistry in 2005.Computed Properties of C47H36N4O The following contents are mentioned in the article:

The development of self-assembling catalysts, although an often-tried approach, has achieved little success so far. Toward the construction of substrate selective catalysts, the authors have self-assembled porphyrin cages based upon the recognition of the templates meso-dipyridyl- (DPyP) or meso-tetrapyridyl-porphyrin (TPyP) by glycoluril-based receptors that are functionalized with two pendant zinc porphyrins. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5Computed Properties of C47H36N4O).

4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Ligands are classified based on the number of lone pair electrons available for the central metal atom, size and charge like anionic, cationic, neutral, monodentate, bidentate, polydentate ligands. Replacing precious metals with cheaper and more environmentally friendly metals is regarded as a highly desirable goal in the field of catalysis.Computed Properties of C47H36N4O
