Phosphonate-functionalized heteroleptic ruthenium(II) bis(2,2′: 6′,2″-terpyridine) complexes

The heteroleptic complexes [Ru(1)(4)][PF6]2, [Ru(2)(4)][PF6]2, [Ru(Phtpy)(4)][PF6] 2, and [Ru(pytpy)(4)][PF6]2 (Phtpy = 4′-phenyl-2,2′:6′,2″-terpyridine, pytpy = 4′-(4-pyridyl)-2,2′:6′,2″-terpyridine, 1 and 2 = 4-methyl ester substituted derivatives of Phtpy and pytpy, 4 = ethyl 2,2′:6′,2″-terpyridine-4′-phosphonate) have been prepared. The single crystal structure of ligand 1 (1 = methyl 4-carboxy-4′-phenyl-2,2′:6′,2″-terpyridine) is reported. The introduction of the 4-methyl ester group causes a small red shift in the MLCT band of the ruthenium(II) complexes and a small shift to a more positive potential for the Ru2+/Ru3+ couple. The new complexes should serve as a useful starting point for development of ruthenium(II) dyes suited for sensitization of p-type semiconductors.

Multi-Readout Logic Gate for the Selective Detection of Metal Ions at the Parts Per Billion Level

Optical sensors utilizing visual responses for the identification of metal ions require reliable molecular systems able to operate selectively in multicomponent solutions. Herein, we report a water-soluble terpyridyl-based ligand that demonstrates effective quantification of parts per billion to parts per million levels of Fe2+, Fe3+, Zn2+, and Ru3+. Whereas the Fe3+and Ru3+ions were found to bind to the ligand to form a monometallic complex, a 2:1 ligand/metal binding stoichiometry was found for the Zn2+and Fe2+complexes. The corresponding metal-binding events were directly translated into distinct colorimetric and spectroscopic logic outputs. Applying molecular logic (Boolean logic operations) to describe these binding events, selective discrimination between the ions was demonstrated.

Preparation of Phosphonated Polypyridyl Ligands to anchor Transition-metal Complexes on Oxide Surfaces: Application for the Conversion of Light to Electricity with Nanocrystalline TiO2 Films

To anchor transition-metal compounds onto metal oxide surfaces 2,2':6',2''-terpyridine-4'-phosphonic acid (4'-PO3H2-terpy) is synthesized; strong surface adhesion as well as efficient charge-transfer sensitization of nanocrystalline TiO2 films has been observed with a ruthenium complex involving this ligand.
