High‐color‐quality phosphorescent white organic light‐emitting diodes utilizing broad‐spectrum yellow emitters

FlexMat, Volume 2, Issue 3, Page 442-451, October 2025.
High‐quality, healthy indoor lighting is increasingly desirable. We present a strategy for constructing low‐energy white organic light‐emitting diodes (WOLEDs) using a blue emitter and a novel broad‐spectrum yellow emitter. The yellow OLEDs, incorporating this emitter, were fully cover the region from green to deep red with a full‐width of half ...

Expedient, Directed Ir‐Catalyzed Diborylation of (Hetero)Biaryls via a Tridentate Ligand

ChemCatChem, Volume 17, Issue 18, September 19, 2025.
The iridium‐catalyzed diborylation of 2‐aryl pyridines and isoquinolines with B2pin2 is reported. Using [Ir(OMe)(COD)]2 and a terpyridine derivative as a tridentate ligand, the heterobiaryls were selectively diborylated at the 2,6‐positions of the carbocycle.

Synthesis of Mixed Phosphine–Phosphine Oxide Ligands by Rh(I)‐Catalyzed C─H Bond Alkylation

ChemCatChem, Volume 17, Issue 16, August 18, 2025.
An efficient method for the synthesis of mixed phosphine–phosphine oxide ligands via Rh(I)‐catalyzed C─H bond alkylation of biarylphosphines was developed. The resulting hemilabile ligands demonstrate high reactivity in Pd‐catalyzed Buchwald–Hartwig coupling with ammonia, achieving excellent yields. This work highlights the potential of mixed phosphine–

Binap and MeO-Biphep complexes of Ru(II). Dicationic ligands as 6e donors. Unexpected cyclometallation in connection with P—C bond breaking

, 2001
A series of cationic and dicationic Ru-arene complexes with Binap (1a) and MeO-Biphep (1b) have been prepared. 13C NMR studies are shown to be useful in connection with recognising the 6e-bonding mode of 1a and 1b in the dications [Ru(1a or 1b)(η6-arene)

Csp3−H Activation without Chelation Assistance in an Iridium Pincer Complex Forming Cyclometallated Products

, 2017
Cyclometallation of 8-methylquinoline and 2-(dimethylamino)-pyridine in an iridium-based pincer complex is described. The C−H activation of 2-(dimethylamino)pyridine is not chelation assisted, which has not been described before for Csp3−H bonds in ...

C–H activation through late transition metal cyclometallation. Addressing selectivity and reactivity problems. [PDF]

, 2015
The ligand-directed C—H activation relies on a coordinating donor atom being in proximity to the C—H bond activated. Cyclometallation of 2-(1-naphthyl)-pyridine – a substrate containing both γ- and δ-positions in proximity to the directing nitrogen atom –

Cyclometalated Ruthenium Dyes for DSSC

Journal of Photopolymer Science and Technology, 2012
A novel thiocyanate-free cyclometalated ruthenium sensitizer for solar cells is designed and developed. Upon anchoring to nanocrystalline TiO2 films, it exhibits a remarkable incident monochromatic photon-to-current conversion efficiency of 83%. The solar cell employing a liquid-based electrolyte exhibits a short circuit photocurrent density of 17 mA ...
