Self-assembled supramolecular cages containing ruthenium(II) polypyridyl complexes.

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 ...

Supramolecular Photochemistry and Solar Cells

Supramolecular photochemistry as well as solar cells are fascinating topics of current interest in Inorganic Photochemistry and very active research fields which have attracted wide attention in last two decades. A brief outline of the investigations in these fields carried out in our Laboratory of Inorganic Photochemistry and Energy Conversion is given here with no attempt of an exhaustive cov...

Synthesis and cytotoxicity of dinuclear complexes containing ruthenium(II) bipyridyl units linked by a bis(pyridylimine) ligand.

Enantiopure dinuclear ruthenium polypyridyl complexes of the form [Ru(2)(LL)(4)L(1)](PF(6))(4) (LL = 2,2'-bipyridine (bpy) or 1,10-phenanthroline (phen); L(1)= C(25)H(20)N(4) a bis(pyridylimine) ligand containing a diphenylmethane spacer) have been synthesized using the chiral building blocks cis-[Ru(bpy)(2)(py)(2)](2+) and cis-[Ru(phen)(2)(py)(2)](2+). These dinuclear ruthenium complexes have ...

Tuning of the Excited State Properties of Ruthenium(II)- Polypyridyl Complexes

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...
