Abstract: An OLED multilayer electroluminescent device includes a cathode, an anode, a light-emitting layer (LEL) disposed therebetween, and charge-transporting layers disposed between (A) the cathode and the light-emitting layer, (B) the anode and the light-emitting layer, or (C) both (A) and (B). The light-emitting layer (LEL) includes a host material and an emitter. The host material includes a high-entropy non-crystallizable molecular glass mixture, which includes hole-transporting capabilities, electron-transporting capabilities, or ambipolar capabilities. The ambipolar capabilities include hole-transporting capabilities and electron-transporting capabilities.
