We report a divergent synthetic strategy and novel design concept that exploit molecular mixtures to create amorphous organic charge-transporting glasses. Using Suzuki鈥揗iyaura cross-coupling reactions, we synthesized well-defined molecular mixtures in a single step. These solution-processable materials are noncrystalline and show good thermal and morphological stabilities. Moreover, they have robust hole and electron mobilities, which make them excellent candidate materials for organic light-emitting diodes. Our general strategy enables the facile synthesis of noncrystalline materials with well-controlled electronic properties.
