Di-ruthenium complex for use as a photosensitizer

What is it about?

Coordination complexes that contain macrocyclic ligands, such as naturally occurring magnesium-porphyrins and iron-porphyrins, play a vital role in biological systems. This paper reports the use of a bipyridyl bis-urea macrocycle as a bridging ligand (μ-L) to synthesize a di-ruthenium complex for use as a photosensitizer.

Why is it important?

We investigated the electronically mismatched Diels–Alder reaction of isoprene and trans-anethole in the presence of complex and visible light as a model system to test the ability of the complex to act as a photosensitizer.
