Abstract:
1. An inverted OLED device, comprising in sequence: a. a substrate; b. a cathode in contact with the substrate; c. second electron-accepting layer including a second electron-deficient organic material constituting more than 50% by volume of the second electron-accenting layer and having a reduction potential greater than −0.5 V vs. a Saturated Calomel; D. an electron-transporting layer; E. at least one light-emitting layer; F. a hole-transporting layer; g. a first electron-accepting layer disposed between the hole-transporting layer and the anode and including a first electron-deficient organic material constituting more than 50% by volume of the first electron-accepting layer and having a reduction potential greater than −0.5 V vs. a Saturated Calomel; and h. an anode.
