Figure 1. Molecular structure of l-PN(THS) oligomers and OLED illustration

Caption

(a) Molecular structure of the l-PN(THS) oligomer series. (b) Band diagram for the materials employed in the OLEDs. TFB (Poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-(4,4?-(N-(4-sec-butylphenyl)diphenylamine)]) and F8BT molecular structures are illustrated respectively above and below the relative band diagrams. (c) OLED architecture including ITO patterned glass substrate, poly(3,4-ethylene dioxythiophene) doped with poly(styrene sulfonate) (PEDOT:PSS) hole-transport layer, TFB electron/exciton blocking layer, F8BT:l-P6(THS) NIR light-emitting layer and Ca/Al cathode.
