Electron Transport Properties of Zn(phen)q Compared with Alq3in OLED

Abstract: We synthesized new electroluminescence materials [(1,10-phenanthroline)(8-hydroxyquinoline)] Zn(phen)q and investigated their electron transport properties. We used Zn(phen)q and Alq 3 for the conductive materials and measured their electron transport properties as a function of the organic layer thickness. The difference between Zn(phen)q and Alq 3 as electron transporting materials suggests that the electrical properties depends on the carrier injection.

“…31 Hence, 6a and 6b should also be suitable to act as the hole-transporting layer in such fabricated devices. However, emission from the Alq 3 layer was only observed in 6a, which indicates that 6a, containing triphenylamine substituent with greater electron-donating capacity, was simultaneously acting as a hole-transporting layer and an emitting layer.…”

“…1050 cm −1 is due to the C-O stretching vibration at the C-O-Ti site. 27 The band around 1406 cm −1 is the formation of a chemical bond between the carboxylic group of modifiers and the brφnsted acid site (i.e., Ti-OH) on the TiO 2 surface. The corresponding structures discussed above are shown in Figure 4b.…”

“…However, the presentation of the second metal ion in the main matrix enhances the film's intensity to oxygen that can control electrical properties. [5] Conventional a-Si is inappropriate for large-area ultra-definition (UD) and 3-dimensional (3D) displays, due to low field effect mobility, and it hardly adapts large size display. In the past decade, AOSs have made tremendous improvement in display industry.…”
