Cross‐linkable hole‐transporting, host, and electron‐transporting materials with a new cross‐linking group, uracil, are designed and synthesized. These compounds exhibited good solubility in common organic solvents and excellent solvent resistance after cross‐linking at a low temperature of 120 °C. The OLED was fabricated by all‐solution processing using cross‐linkable synthetic compounds, except for the electrodes. This device exhibited a current efficiency of 39.2 cd A −1 and a power efficiency of 15.3 lm W −1 .
