Spectroscopic and electrochemical recognition of H2PO4- based on a ruthenium complex with 2-picolinamide
A ruthenium polypyridyl complex 4(PF6) with 2-picolinamide as an anionic N <^> N bidentate ligand is synthesized and characterized, including single-crystal X-ray analysis. As an effective anion receptor in CH2Cl2, complex 4(PF6) shows selective spectroscopic and electrochemical recognition towards H2PO4- over other anions tested (F-, Cl-, Br-, I-, HP2O73-, HSO4-, AcO- and NO3-). Job’s plot and mass spectral analyses support that an adduct is formed between 4 and H2PO4- with a 1:2 binding stoichiometry. The absorption spectral titration of 4(PF6) with H2PO4- yields a global association constant in the order of 10 8 L-2.mol(-2) and an optical detection limit of 1.4 x 10(-6) mol.L-1. In response to the presence of H2PO4-, the Ru(II/III) redox couple of 4(PF6) displays a two-wave behavior accompanied by a large negative shift from + 0.74 to + 0.45 V vs Ag/AgCl. H-1 NMR spectral titration analyses suggest that effective hydrogen bonding interactions are present between 4 and H2PO4-, which are believed responsible for the observed spectroscopic and electrochemical response of 4(PF6) toward H2PO4-.
