Ruthenium polypyridyl phototriggers: from beginnings to perspectives.

Construction of a photoactive supramolecular system based on a platinum(II) bis-acetylide building block incorporated into a ruthenium(II) polypyridyl complex.

A new ruthenium(ii) polypyridyl-platinum(ii) diethynyl triad containing 3-ethynylphenanthroline linked by platinum(ii) bis-tributylphosphine organometallics, Ru(ii)-Pt(ii)-Ru(ii), and platinum(ii) bis-ethynylphenanthroline complex has been prepared. The ruthenium(ii)-metal triads, Ru(ii)-M-Ru(ii) (M = Pt(ii) and Au(i)), showed typical MLCT absorption bands and a lowest energy pi-pi* absorption ...

Rapid electrochemically induced linkage isomerism in a ruthenium(II) polypyridyl complex.

Rapid and complete switching between the N6 and the N5O donor set induced by changing the metal oxidation state has been observed for a new structural motif based on a ruthenium(II) polypyridyl complex.

Observations on the low-energy limits for metal-to-ligand charge-transfer excited-state energies of ruthenium(II) polypyridyl complexes.

The 77 K emission spectral maxima of bis(bipyridine)ruthenium(II) complexes are found to approach a limit at energies below about 14,000 cm(-1). There is also evidence for related low-energy excited-state limits in some other classes of ruthenium polypyridyl complexes. The shapes of the vibronic sidebands found in these limits differ from those of complexes that emit at higher energies. These l...

Ruthenium polypyridyl peptide conjugates: membrane permeable probes for cellular imaging.

Two novel polyarginine labelled ruthenium polypyridyl dyes are reported, one conjugated to five, (Ru-Ahx-R5), and one to eight arginine residues, (Ru-Ahx-R8); both complexes exhibit long-lived, intense, and oxygen-sensitive luminescence; (Ru-R8) is passively, efficiently and very rapidly transported across the cell membrane into the cytoplasm without requirement for its permeablisation.
