The photoelectrochem. of a series of porphyrins containing an alkyl chain terminated with imidazolyl, is described. Indium-tin oxide electrodes deposited with porphyrins using the Langmuir-Blodgett (LB) technique exhibit high photocurrent values under ambient condition. Action spectra of the photocurrent generation are coincident with the absorption of the LB film-modified electrodes, indicating that the dye aggregates in the LB film are responsible for the photocurrent. The bias voltages that may influence the photocurrent have also been investigated. The photocurrents varied with the side chain length; the compound with a longer chain but not with the shortest chain generated the maximum photocurrent. To interpret such a special case, a possible mechanism is suggested. This study involved multiple reactions and reactants, such as 4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5COA of Formula: C47H36N4O).
4-(10,15,20-Tri-p-tolylporphyrin-5-yl)phenol (cas: 57412-08-5) belongs to catalyst ligands. The atoms and molecules used as ligands are almost always those that are capable of functioning as the electron-pair donor in the electron-pair bond (a coordinate covalent bond) formed with the metal atom. The actual catalysts are metal complexes that are prepared from ligands and appropriate metal precursors.COA of Formula: C47H36N4O
