Bright white light emission in rubrene‐doped organic LEDs has been demonstrated using spiro compounds—such as spiro‐TAD, shown in the Figure—with high glass transition temperatures. These materials show high morphological stability for hole transport and emission of blue light, and thus still operate at temperatures well above 100 °C. The devices give a maximum luminance of 11800 cd/m 2 .
