Ruthenium Terpyridine Complex Showing Stable Photocatalytic Hydrogen Evolution Under Red Light
Abstract
We report herein the synthesis of a tridentate ligand (tris-4,4',4''-(4'''-pyridyl)-2,2':6',2''-terpyridine) and its corresponding homoleptic ruthenium(II) complex, which shows stable hydrogen photoproduction under red light (TON of 174 molH2·molPS-1 after 210 hours). A sustained activity under blue and green lights is also observed with TONs above 360 molH2·molPS-1 after 168 hours.
