Abstract

The possibility of using a single light-emitting layer consisting of newly synthesized fluorescent small organic molecules of D-A-π-A type incorporated into a conductive matrix together with an electron conductive Alq layer in order to form radiation in candle light-style OLEDs was shown for the first time. A record low color temperature of 1722 K OLED radiation was achieved, which is by 80 K lower than that of the best devices reported previously.

摘要

首次展示了使用由新合成的 D-A-π-A 型荧光小分子组成的单一发光层的可能性，该小分子掺入到导电基质中，并与电子导电的 Alq 层一起形成辐射，以便在烛光灯式 OLED 中形成辐射。实现了创纪录的低色温 1722 K OLED 辐射，比以前报道的最佳器件低 80 K。
