Four novel thermally activated delayed fluorescence (TADF) materials with phenoxazine (PXZ) and 9,10-dihydro-9,9-dimethylacridine (ACR) as electron donors and 1,2-diphenyl-1H-phenanthro[9,10- d]imidazole (PI), and 1,2-diphenyH H-benzo[d]imidazole (Bl) as electron acceptors (PXZ-PI, ACR- Pl, PXZ-BI, ACR-BI) were designed and theor. investigated for blue OLED emitter. Using DFT and TDDFT calculations, we gained the electron distribution of HOMO and LUMO and the energy of the lowest singlet (S1) and the lowest triplet (T1) excited states. All of the materials have a small spatial overlap between HOMO and ã-UMÖ because of the relatively large dihedral angle between the Ph ring and the acceptor moiety. In terms of the energy difference (ΔEST) between the (S1) state and the T1, state, PXZ-PI, PXZ-BI, and ACR-BI showed the small ΔEST. However, ACR-PI showed the large ΔEST. Among the TADF materials, we showed that ACR-BI would have the best TADF properties in terms of small ΔEST and blue LED emitters.
