  • Abstract In this study, a new blue Thermally Activated Delayed Fluorescence (TADF) , we call it ” BTZ-PXZ ” is designed and synthesized. The ΔEST of 4,7-di(10H- phenoxazin-10-yl)benzo[c][1,2,5]thiadiazole (BTZ-PXZ) is lower than 4,7-bis(9H- carbazol-9-yl)benzo[c][1,2,5]thiadiazole (BTZ-CZ), 4,7-bis(9,9-dimethylacridin- 10(9H)-yl)benzo[c][1,2,5]thiadiazole (BTZ-DMAZ) and N4,N4,N7,N7-tetraphenyl- benzo[c][1,2,5]thiadiazole-4,7-diamine (BTZ-DPA) which we can find some related papers in Journal of Materials Chemistry C. In this way, BTZ-PXZ can reduce the effect of singlet–triplet annihilation (STA) and triplet–triplet annihilation (TTA) and at the same time increase EQE.
    In past related research, only Fan Ni et al.[59] applied BTZ in TADF. That is BTZ-CZ, BTZ-DMAZ and BTZ-DPA. We modify the compound to get BTZ-PXZ. The feature is that can separate HOMO from LOMO and make ΔEST lower.
    We get ΔEST(0.0087eV) of BTZ-PXZ from Gaussian 09. The lowerΔEST gives a basis for our study and we start to synthesize BTZ-PXZ. We find the best method to synthesize BTZ-PXZ. In NMR spectrum, we can discover this material is very pure that can be used directly in component process.
