Single-Layer Electroluminescent Devices and Photoinduced Hydrogen Production from an Ionic Iridium(III) Complex
Abstract
We report the electronic structure and diverse applications of a highly luminescent ionic transition metal complex, [Ir(dF(CF 3 )ppy) 2 (dtbbpy)](PF 6 ) (where dF(CF 3 )ppy = 2-(2,4-difluorophenyl)-5-trifluoromethylpyridine and dtbbpy = 4,4‘-di- tert -butyl-2,2‘-dipyridyl). The large HOMO−LUMO gap (Δ E = 3.06 V) enabled high-energy electroluminescence from the complex. Single-layer devices were fabricated and found to emit blue-green light (500 nm). The strong reducing strength of the excited state ( E * ox = 1.21 V) enabled effective catalysis of the photoinduced reduction of H 2 O to H 2 . It was found that the relative quantum yield of hydrogen was over an order of magnitude improved from the standard photosensitizer Ru(dmphen) 3 2+ (dmphen = 4,7-dimethyl-1,10-phenanthroline).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
