Intramolecular-locking modification enables efficient asymmetric donor–acceptor–donor′ type ultraviolet emitters for high-performance OLEDs with reduced efficiency roll-off and high color purity

Developing high-performance ultraviolet organic light-emitting diodes with low efficiency roll-off and high color purity remains challenging due to their inherent wide-bandgap characteristics. In this work, we present an intramolecular noncovalent…
