dc.description.abstract | Conjugation-extended carbazolophane donors, dicarbazolophanes ( DCzp ), were designed and synthesized using a multifold stepwise Pd-catalyzed Buchwald–Hartwig amination/ring cyclization process. Furthermore, elaboration of the DCzp core is possible with the introduction of pendant carbazole derivative groups. This provides a way to tune the optoelectronic properties of the thermally activated delayed fluorescence (TADF) compounds DCzpTRZtBu , dtBuCzDCzpTRZtBu , and dMeOCzDCzpTRZtBu . Solution-processed organic light-emitting diodes (OLEDs) were fabricated and achieved a maximum external quantum efficiency (EQEmax) of 8.2% and an EQE of 7.9% at 100 cd/m2. | |
