![عکس صفحه اول مقاله: Substituted Diindenopyrazinediones with symmetrical Polyalkyl-carbazole for high-efficiency blueish green solution-processable OLED Substituted Diindenopyrazinediones with symmetrical Polyalkyl-carbazole for high-efficiency blueish green solution-processable OLED](/preview/png/6469472.png)
- We have designed and synthesized two kinds of solution-processable Substituted Diindenopyrazinediones with improved carrier transport.
- Solution-processed device shows PEmax and CEmax of 2.20 l m Wâ1 and 2.49 cd Aâ1.
- By fine-tuning their carries transfer and injection barriers, DTPADIPY-TCz shows a relatively low efficiency roll-off.
Much effort has been devoted to design and synthesize this solution-processable OLEDs, Some significant advances have been achieved with the power efficiencies. However, most of them still lag behind those of evaporated non-doping OLEDs. Two novel peripheral Polyalkyl-carbazole substituted Diindeno-pyrazinediones have been developed for highly-efficient and solution-processable OLEDs. Provide high efficient materials for the solution-processed to reduce costs of OLEDs. By fine-tuning their carriers transfer and injection barriers, solution-processed device based on DTPADIPY-TCz shows highly efficient bluish green emission with a maximum power efficiency (PE) of 6.88 lm Wâ1, which is among the highest reported to date for solution-processable fluorescent OLEDs with a relatively low efficiency roll-off.
