Expanded cyclophanes for switchable capture/release of metal complexes
… receptors with pentamethylene chains. Ru(II) polypyridine complexes Ru(II)(bpy)3 and Ru(II)(phen)3, which have similar D3 symmetry conformation to cyclophane receptors, can be encapsulated into the cavity of the receptors to form inclusion complexes in water. The switchability of cyclophane …

Photochemistry of a Series of Weakly Coupled Dinuclear Ruthenium(II) Complexes
… method was developed for symmetric ruthenium(II) polypyridine complexes with the form L2Ru(diphen)RuL2. The scope of the reaction was investigated in regards to the ligands, bridging ligands, and starting materials. Several ligands were successful in the synthesis, including 2,2’-bipyridine (bpy), …

Synthesis of heteroaromatic ruthenium dyes for use as electron reservoirs in dye-sensitized solar cells
<p>Increasing the usable portion of solar spectrum is a key factor in increasing the efficiency of modern solar cells. The near-IR region of the solar spectrum is often underutilized as a means of energy production, as the photons in this region do not contain enough energy to promote electrons to …
