| Popis: | The triazine compound 4,4′-bis-[2-(4,6-diphenyl-1,3,5-triazinyl)]-1,1′-biphenyl (BTB) was developed for use as an electron transport material in organic light emitting devices (OLEDs). The material demonstrates an electron mobility of ∼7.2 × 10−4 cm2 V−1 s−1 at a field of 8.00 × 105 V cm−1, which is 10-fold greater than that of the widely used material tris(8-hydroxyquinoline) aluminum (AlQ3). OLEDs with a BTB electron transport layer showed a ∼1.7–2.5 V lower driving voltage and a significantly increased efficiency, compared to those with AlQ3. These results suggest that BTB has a strong potential for use as an OLED electron transport layer material. |
