Let¡¯s face it, organic chemistry can seem difficult to learn. 6287-82-7. Especially from a beginner¡¯s point of view. Like 6287-82-7, Name is 2,3-Dibromobenzo[b]thiophene. In a document type is Article, introducing its new discovery.
Thermally-stable 2,3-diphenylated benzotiophene containing host materials for red phosphorescent organic light-emitting diodes
This study reports a series of benzo[b]thiophene (BT) derivatives with good electronic properties as host materials for red phosphorescent organic light-emitting diodes (PHOLEDs). We applied thermally-stable materials for red PHOLEDs which contain BT and carbazole moieties which also provide a good charge transport ability, as well as a good charge confinement effect (T1 > 2.25 eV). To control the appropriate charge transporting ability, two different structures having one or two carbazole units connected to the single BT moiety were prepared. Using this approach, we found that the material with a single carbazole and a single BT unit showed the best current efficiency and external quantum efficiency (up to 23.6 cd/A and 12.8%, respectively). The results of the experiment also suggest that BT could be used as an electron-transporting unit when utilized with carbazole moiety, although it has previously been utilized as a p-type material.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 6287-82-7, and how the biochemistry of the body works.6287-82-7
