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.
OLED materials with uracil that are capable of cross‐linking have been successfully synthesized. The hydrogen bonding between the uracil groups gave effective solvent resistance, such that the OLED materials were not soluble in the organic solvents. The OLED was fabricated by all‐solution processing using cross‐linkable synthetic compounds, except for the electrodes. The device fabricated using the cross‐linkable small molecules exhibited comparable device performance to the device fabricated by the thermal evaporator. This indicates that the new cross‐linkable materials can serve as good alternatives to vacuum‐deposition materials.
