A polymeric layer for an anode buffer is a promising organic light-emitting diode (OLED) component providing some merits such as mechanical film robustness, high temperature stability, smoothened surface and fabrication convenience. In this study, the comparison between some polymeric anode buffer systems for small molecule-based OLEDs was carried out. The device with BFE buffer, one of the well-known conjugated polymers with a triphenylamine moiety, shows the best performances which are further improved by annealing BFE layer at a high temperature of 250 degrees C.
