The present invention relates to electronic devices, especially electroluminescent devices, comprising compounds of formula (I), and/or (II), especially as host for phosphorescent emitters, electron transporting materials, or emitter materials. The hosts may function with phosphorescent materials to provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.

Citrate trisulfonic acid (CTSA), as a novel recyclable and eco‐benign organocatalyst, was employed for the efficient and one‐pot synthesis of trisubstituted imidazoles and tetrasubstituted imidazoles using aldehydes, ammonium acetate or aniline, and benzoin, benzyl, or 9,10‐phenanthrenequinone under solvent‐free conditions providing high to excellent yields. CTSA is easily prepared via the reaction
