Pt(II) Complexes with High Color Purity in Blue Organic Light-Emitting Diodes via Ligand Engineering

Student

Description:

The planar structure of the Pt(II) complex makes it susceptible to intermolecular interactions. To address this, bulky groups like 3,5-di-tert-butylphenyl in Pt1 and 2,6-diisopropylphenyl in Pt2 were introduced. This modification resulted stable spectra at high doping concentrations, a narrow full-width at half maximum (FWHM) of 18 nm, and a maximum external quantum efficiency (EQE) of 21.4%.
