Bright Blue‐Emitting Ce³⁺ Complexes with Encapsulating Polybenzimidazole Tripodal Ligands as Potential Electroluminescent Devices

Abstract

Sky-blue research: Studies of the photoluminescence and electroluminescence of a series of Ce3+ coordination complexes with tripodal benzimidazole ligands reveals effective energy transfer from both metal- and ligand-based transitions and efficient blue metal-centered emission. A blue-emitting LED device was fabricated using one such cerium complex, suggesting their potential application as light-emitting materials.
