OLED devices based on hexaphenylsilole (HPS) have been fabricated. These devices emit very bright greenish‐blue light, up to 55,880cd/m 2 at 16V. Emission starts at 2.6V, and reaches 100‐ cd/m 2 and 10,790‐cd/m 2 at 5V and 10V respectively. The maximum electroluminescence (EL) efficiency and power efficiency are 20‐cd/A and 12.8‐lm/W, respectively. The maximum external quantum efficiency is 7%.
