The present invention provides an OLED multilayer electroluminescent device that includes a cathode, an anode, a light-emitting layer (LEL) disposed there between, 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.

According to Mike Molaire, Molecular Glasses’ CEO and Founder, “OLEDIQ™ materials are amorphous, soluble small molecules that are non-crystallizable, which prevents aggregation of dopant emitters. This means OLEDIQ™ produces significant improvements in OLED lifetime and high reliability. This is an ideal platform for high-efficiency, long-lasting blue OLED. OLEDIQ™ materials can be used for both the vacuum-thermal deposition production process, as well as inkjet printing without any modification”.
