Boronate- and borinate-based π-systems for blue thermally activated delayed fluorescence materials†
Abstract
Thermally activated delayed fluorescent molecules containing boronate-ester, -thioester, and borinate-ester moieties as electron-accepting units were designed and synthesized. OLEDs with a borinate-ester-based emitter exhibited blue electroluminescence with CIE chromaticity coordinates of (0.15, 0.15).
