dc.descriptionSupramolecular species combining ruthenium(II) polypyridines and tetrapyridylporphyrins (TPyP) have been employed in electrochemical and molecular sensing devices, because of their unique synergistic properties. In this work, a new tetraruthenated porphyrin, 4-TRoxPyP has been synthesised, encompassing four pyridine bridged [Ru(Cl-tpy)(ox)] complexes (Cl-tpy = chloroterpyridine, ox = oxalate ion). Such species exhibit characteristic electronic transitions of porphyrin and ruthenium polypyridine complexes, such as a Soret band at 414 nm, Q bands at 514 nm, 557 nm and 588 nm and a ruthenium-to-terpy charge-transfer band at 643 nm. A typical tetraruthenated porphyrin redox process has been observed at 0.72 V versus NHE, associated with the peripheral Ru3+/(2+) complexes. Their thin films have been prepared by drop casting onto a glassy carbon electrode, and successfully employed in nitrite analysis, by monitoring the chronoamperometric response at the Ru3+/2+ redox gate. A linear relationship between the anodic peak current and concentration of the analyte has been observed from 0 to 0.10 mmol L (1), with a nitrite detection limit of 7.60 mu mol L-1.
