Non-Dopant Electroluminescent Devices Based on Benzoxazinone Derivative as Strong Fluorescence in Solid Film

Abstract:

The orange fluorescent compound 2-[2-(p-toluenesulphonylamino)-5-chlorophenyl]-6- chloro-4H-3,1-benzoxazin-4-one (Cl-TSB) was synthesized by reacting 2-amino-5-chlorobenzoic acid with p-toluenesulphonyl chloride. The strong photoluminescent peak was at 544 nm in solid film. HOMO and LUMO energy levels were calculated -5.00 and -1.82 eV. The multilayer organic light-emitting devices (OLEDs) ITO/NPB/Cl-TSB/BCP/TPBi or Alq3/LiF/Al were fabricated. The electroluminescent peaks of all devices were at ca. 620 nm with luminance of over 100 cd/m². The characteristics of devices demonstrated that Cl-TSB was an orange emitter suitable for OLED.
