Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1008-89-5, is researched, Molecular C11H9N, about Rigid Bridge-Confined Double-Decker Platinum(II) Complexes Towards High-Performance Red and Near-Infrared Electroluminescence, the main research direction is platinum double decker bridge confined red near IR electroluminescence; NIR emission; OLEDs; metallophilicity; platinum complexes; red emission.Related Products of 1008-89-5.
A mol. design to high-performance red and near-IR (NIR) organic light-emitting diodes (OLEDs) emitters remains demanding. Herein dinuclear Pt(II) complexes featuring strong intramol. Pt···Pt and π-π interactions were developed by using N-deprotonated α-carboline as a bridging ligand. The complexes in doped thin films exhibit efficient red to NIR emission from short-lived (τ = 0.9-2.1 μs) triplet metal-metal-to-ligand charge transfer (3MMLCT) excited states. Red OLEDs demonstrate high maximum external quantum efficiencies (EQEs) of ≤23.3% among the best PtII-complex-doped devices. The maximum EQE of 15.0% and radiance of 285 W sr-1 m-2 for NIR OLEDs (λEL = 725 nm) are unprecedented for devices based on discrete mol. emitters. Both red and NIR devices show very small efficiency roll-off at high brightness. Appealing operational lifetimes also were revealed for the devices. This work sheds light on the potential of intramol. metallophilicity for long-wavelength mol. emitters and electroluminescence.
