摘要

Abstract

Efficient deep-red organic light-emitting diodes (OLEDs) were investigated based on the blend of poly[2- methoxy-5-(2'-ethyl-hexyloxy)-1

4-phenylene vinylene] (MEH-PPV) with 4

7-bis(5-(7-(9H-carbazol-9-yl)-9

9-dioctyl-9H-fluoren- 2-yl)thiophen-2-yl)benzo[c] [1

5] thiadiazole (compound 1). By optimizing the blend ratio

the turn-on voltage of the devices was significantly reduced from 4.9 V to 2.4 V. A highest external quantum efficiency of 2.56% was achieved at a blend ratio of 95:5 (wt) for compound 1: MEH-PPV. The CIE coordinate was measured to be (0.70

0.30)

with the luminescence peak at around 680 nm. Based on experimental observations the improvement mechanism is described.
