Enhancing Triplet–Triplet Annihilation Upconversion Performance Through Anthracene–Carbazole Interactions for Organic Optoelectronic Applications
Three carbazole-substituted anthracene 2CbzAn, 26CbzAn, and 246CbzAn have been developed. The introduction of these carbazole substituents could generate more triplet states with energy levels close to 2× E(T1) that could successfully facilitate the triplet-triplet annihilation upconversion (TTA-UC) process to achieve high upconversion quantum yield (UCQY). This observation aligns with the Adachi theory about TTA-UC mechanisms. In organic light-emitting diode (OLED) device investigation, in a non-doped state show an external quantum efficiency (EQEmax) of 5.82% with exceptional pure-blue emission (CIEy of 0.101), and the DPaNIF doped DMPPP/26CbzAn bilayer structure reaches an impressive EQEmax of 11.12%.
