Organic Light-Emitting Materials and Devices, 2nd Edition

3.7  Conclusion and Remarks

While the individual materials described in the preceding sections are all valuable and in many cases essential for the realization of good, long-lived performance in OLED devices, it is equally true that the materials themselves are only a small part of the OLED story. As frequently alluded to above, the precise architecture into which the materials are placed is crucially important to device performance. Furthermore, while the bulk materials properties themselves, and especially their purities, are important, the interfaces formed between different materials are equally critical. Both chemical and morphological effects at any of the materials’ interfaces in a device can have profound effects on the overall device ...
