N2 - (Equation Presented). Five carbazole end-capped heterofluorenes (CzHFs) designed by structurally mimicking 4,4′-N,N′-dicarbazole-biphenyl (CBP) via connecting the biphenyl core of CBP with the linking atom of C, P, N, O, and S, respectively, were synthesized successfully, and their optoelectronic properties were investigated. The theoretical calculations and experimental results demonstrate that CzHFs are potential green, red, and even blue hosts for phosphorescent light-emitting diodes (PHOLEDs) with more desirable localization and energy levels of HOMO and LUMO and also higher triplet energy than CBP.
