| چکیده مقاله |
| Ruthenium pincer complexes (RPC) were studied for various properties in catalysis, electrocatalisis, medicine and enviremental[16-21].Among different pincer ligands, the symmetric pincer ligands bearing two same lateral donor arms on the central donor unit have been synthesized in the early stage [1]. One of these ligands are P^N^P,s, classified in aliphatic or aromatic structure based on their backbone [2]. PNP pincer ligands that includ triazine backbone, and phosphorus coordinating group were broadly used in transition metal chemistry [3]. In this study, ruthenium pincer complexes {[Ru(PNP–Ph)Cl2(PPh3)] (1) based on PNP-Ph (N, N´-Bis(diphenylphosphino)-2,6-diamino-4-phenyl-1,3,5-triazine) was prepared. The pincer ligands and complexes were characterized by FT-IR, UV-Vis, 1H NMR, 13C NMR, and 31P NMR. The pincer complex was used as a homogeneous electrocatalyst to oxygen evolution reaction in acetonitrile solution. Cyclic voltammetry studies on OER reaction, demonstrate that increasing concentration of KOH, causes an increase in current density, a good evidence to O2 evolution. High electrocatalitical properties were observed using the PNP pincer complexes for oxygen evolution |
