Red-light-driven photocatalytic hydrogen evolution using a ruthenium quaterpyridine complex†
Abstract
A high-temperature, microwave synthesis of [Ru(qpy)3]2+ (qpy = 4,4′:2′,2′′:4′′,4′′′-quaterpyridine) affords the photosensitiser in quantitative yield. The complex produces H2 photocatalytically in a range extending from the UV region of the spectrum to the red with greater efficiency when compared to [Ru(bpy)3]2+.
