Herein, we report the synthesis, characterization and potential application of bis(4-(7,9,10-triphenylfluoranthen-8-yl)phenyl)sulfone (TPFDPSO2) and 2,8-bis(7,9,10-triphenylfluoranthen-8-yl)dibenzo[b,d]thiophene 5,5-dioxide (TPFDBTO2) as electron transport as well as light emitting materials. These fluoranthene derivatives were synthesized by oxidation of their corresponding parent sulphide compounds which were prepared via Diels-Alder reaction. These materials exhibit deep blue fluorescence emission in both solution and thin film, high PLQY, thermal and electrochemical stability over a wide potential range. Hole-only and electron-only devices were fabricated to study the charge transport characteristics and predominant electron transport property comparable with well-known electron transport material, Alq 3 , was observed. Further, bilayer electroluminescent devices were fabricated utilizing these fluoranthene derivatives as electron transport as well as emitting layer and device performance was compared with their parent sulphide molecules. The EL devices fabricated with these molecules displayed bright sky blue color emission and 5-fold improvement in EQE with respect to their parent compounds.
