Comparison of the optoelectronic properties of oxidized and non-oxidized substituted benzothiophene. Application to solution air-processed OLEDs
Résumé
Benzothiophenes and benzothiophene S,S-dioxide substituted with triphenylamines at positions 3,5,6 and 2,4,7 were synthesized in 2 or 3 steps and exhibited emission properties in both solution and solid states. OLED devices were fabricated through air process spin-coating, except for the silver cathode which was evaporated under vacuum. A flexible device based on 2,4,7trimethoxyphenylbenzothiophene S,S-dioxide was successfully printed on PET on large surface .
