The synthesis of covalently linked tetraarylporphyrin dimers was written by Little, Robert G.. And the article was included in Journal of Heterocyclic Chemistry in 1978.SDS of cas: 57412-08-5 The following contents are mentioned in the article:
Porphyrin dimers, e.g. I, were prepared The synthesis involves the reaction of dibromoalkanes with phenolic porphyrins, such as 5-(4-hydroxyphenyl)-10,15,20-tritolylporphyrin, to form ¦Ø-bromoalkyl porphyrin ethers. The latter compounds are then reacted with a second phenolic porphyrin to give porphyrin dimers. A mixed metalloporphyrin dimer was prepared which contains both V(IV) and Cu(II). The compounds were examined spectroscopically. The free-base porphyrin dimers show a splitting of the intense Soret band. This is interpreted as indicative of weak singlet energy transfer between the covalently linked porphyrins. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5SDS of cas: 57412-08-5).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. Ligand design occupies a central place in organic synthesis and catalysis. The actual catalysts are metal complexes that are prepared from ligands and appropriate metal precursors.SDS of cas: 57412-08-5
