- Abstract
The design and synthesis of ruthenium tris‐diimine photosensitizers appropriately functionalized to be (i) anchored onto transparent conductive oxides (TCO) and (ii) covalently coupled with a water‐splitting catalyst represents an important target for solar fuel production in dye‐sensitized photoelectrochemical cells (DS‐PECs). In this study, two different synthetic routes to prepare heteroleptic [Ru(4,4′‐(CH2PO3Et2)2‐bpy)2(N^N)](PF6)2 complexes are evaluated, the scope and limitations of the organometallic pathway involving half‐sandwich η6‐arene ruthenium complexes as synthetic intermediates being especially studied. The spectroscopic and electrochemical characterization of a series of novel structures varying by the nature of the third diimine N^N ligand is reported.
