An efficient photochemical synthesis of conformationally restricted quinone-substituted porphyrins was written by Osuka, Atsuhiro;Morikawa, Soichi;Maruyama, Kazuhiro;Hirayama, Satoshi;Minami, Takaaki. And the article was included in Journal of the Chemical Society, Chemical Communications in 1987.SDS of cas: 57412-08-5 The following contents are mentioned in the article:
The title porphyrins I (R = 2-OR1, 4-OR1; R2-R4 = H; R2 = H, Cl, Br, Me, R3R4 = CH:CHCH:CH) were obtained by self-sensitized photochem. coupling of I (R = 2-OH, 4-OH) with R1R5 (R5 = Cl, Br). The difference between donor oxidation and acceptor red redox potentials is very similar in I (R = 2-OR1) and I (R = 4-OR1). Fluorescence quenching was inefficient in conformationally restricted I (R = OR1). 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, in chemistry, any atom or molecule attached to a central atom, usually a metallic element, in a coordination or complex compound. And they often provide a convenient approach to fine-tuning the performance of known catalysts.SDS of cas: 57412-08-5
