Abstract
A new carbazole-containing polyacetylene (PA) was used as a host material in the construction of red phosphorescent LEDs with a configuration of ITO/PEDOT:PSS/host:btp2Ir(acac)/BCP/Alq3/LiF/Al. Compared with PVK as a host in the same device, The PA as a host has enhanced the quantumefficiency up to 1.4 fold. The efficiency of the device can be further improved 4.5 fold by using a BAlq layer instead of BCP/Alq3 layers, and external quantum efficiency of 4.1% photons/electron has been achieved.
