Abstract
<jats:title>Abstract</jats:title><jats:p>Light‐emitting electrochemical cells (LECs) with a simple device structure were prepared by using heteroleptic bis(tridentate) ruthenium(II) complexes [<jats:bold>1</jats:bold>](PF<jats:sub>6</jats:sub>)<jats:sub>2</jats:sub>–[<jats:bold>3</jats:bold>](PF<jats:sub>6</jats:sub>)<jats:sub>2</jats:sub> as emitters. The push‐pull substitution shifts the emission energy to low energy, into the NIR region. The devices emit deep red light up to a maximum emission wavelength of 755 nm [CIE (International Commission on Illumination) coordinates: <jats:italic>x</jats:italic> = 0.731, <jats:italic>y</jats:italic> = 0.269 for [<jats:bold>3</jats:bold>](PF<jats:sub>6</jats:sub>)<jats:sub>2</jats:sub>], which, to the best of our knowledge, is the lowest emission energy for LECs containing bis(tridentate) ruthenium(II) complexes. A device structure of ITO/PEDOT:PSS/ruthenium(II) complex/Ag was used, and the thickness of the emitting layer was measured by AFM [ITO: indium tin oxide, PEDOT: poly(3,4‐ethylenedioxythiophene), PSS: poly(styrenesulfonate), AFM: atomic force microscopy]. To enhance the external quantum efficiency (EQE), cells were fabricated with and without poly(methyl methacrylate) (PMMA) as additive in the emitting layer.</jats:p>
