摘要：

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 similar to 7.2 x 10(-4) cm(2) V-1 s(-1) at a field of 8.00 x 10(5) V cm(-1), which is 10-fold greater than that of the widely used material tris(8-hydroxyquinoline) aluminum (AIQ(3)). OLEDs with a BTB electron transport layer showed a similar to 1.7-2.5 V lower driving voltage and a significantly increased efficiency, compared to those with AIQ3. These results suggest that BTB has a strong potential for use as an OLED electron transport layer material. (C) 2007 Elsevier B.V. All rights reserved.
