Controlling molecular orientations in non-crystalline thin films fabricated from small molecules by varying the substrate temperature during the vapor deposition, influences of molecular orientation in organic light-emitting diodes were investigated. With the randomly oriented host matrix in a light-emitting layer, efficiency roll-off was suppressed by 30% at a current density of 100 mA cm −2 , while the external electroluminescence quantum efficiency was greatly enhanced by 24% with the
