Organic light-emitting diodes (OLEDs) fabricated using wet process has attracted great interests because of the usefulness for large-area display and lighting. Conjugated polymers suitable for the process are prepared using Suzuki-Miyaura coupling reaction. In this report, we show the effect of the preparing and purifying methods of polymer on the properties of the device. In addition, a newly designed crosslinkable hole-injection/transport oligomer, which is applicable for multilayered and printed OLED, is demonstrated.
