Enhancing thermally activated delayed fluorescence characteristics by intramolecular B–N coordination in a phenylpyridine-containing donor–acceptor π-system†
Abstract
An efficient thermally activated delayed fluorescence emitter based on an N-heteroarene acceptor bearing an intramolecularly coordinated boryl group was developed. The impact of the B–N coordination on the optoelectronic properties and electroluminescence performance of devices was investigated.
