The search for affordable high performance electrode materials in photoelectrochemical hydrogen production by solar water splitting is an ongoing quest. Hematite a photoanode material with electronic band gap suitable efficient absorption of visible light cell (PEC). Although its poor structure makes hematite controversial candidate PEC, it remains promising because earth abundant, chemically stable and low cost – necessary prerequisites PEC to become competitive cost-efficient fuel economy....

Abstract The archetype ionic transition‐metal complexes (iTMCs) [Ir(ppy) 2 (bpy)][PF 6 ] and (phen)][PF ], where Hppy = 2‐phenylpyridine, bpy 2,2′‐bipyridine, phen 1,10‐phenanthroline, are used as the primary active components in light‐emitting electrochemical cells (LECs). Solution solid‐state photophysical properties reported for both interpreted with help of density functional theory calculations. LEC devices based on these exhibit long turn‐on times (70 160 h, respectively) low external...
The oligopyridine 6′,6″-bis(2-pyridyl)2,2′ : 4,4″ 2″,2″′-quaterpyridine (L) has been prepared. It may be regarded as a 'back-to-back' analogue of the well known 2,2′ 6′2″-terpyridine (terpy). Complexes with ruthenium(II) and palladium(II) have characterised. diruthenium(II) complex cation [(terpy)RuLRu(terpy)]4+ shown to exhibit no Ru–Ru interactions, behaves two non-interacting Ru(terpy)2 units.
