(1). Title: Layered tetraoctylammonium bromide as an electron-injection layer for cathode-independent

high-efficiency polymer light diodes

Abstract: Tetraoctylammonium bromide (TOAB), a general kind of quaternary ammonium salts, was spun on the surface of a green-emissive poly(9,9-dialkylfluorene) derivative (G-PF) to fabricate cathode-independent polymer light-emitting diodes (PLEDs). The electroluminescent efficiencies are 15.4, 11.4, and 9.1 cd/A, respectively, when TOAB was used with Al, Ag, or Au as a cathode, being even better than that of the device with Ca/Al as a cathode (6.1 cd/A). The molecular nanomorphologies of TOAB deposited on G-PF were investigated by the synchrotron X-ray diffraction to show that TOAB molecules can be nucleated on the hydrophobic G-PF surface and self-assembled into a highly ordered lamellar structure by the spin-coating process. This unique structure results that the suitable molecular dipoles between N⁺ and Br^- significantly improve electron-injection ability from stable metals to G-PF.

The direction of the molecular dipole between N⁺ and Br^- can also be reversed on a hydrophilic ZnO for the use of an efficient electron injection layer in an inverted device. The self-assembly molecules of TOAB create an anisotropic dipole on the basis of hydrophilic or hydrophobic surfaces, being

potentially used as an efficient electron-injection layer in any applicable fields.

(2). Title: Effect of annealing of ZnO on the performance of inverted PLED based on SAM/ZnO as an

electron-injection layer

Abstract: An efficient electron injection/hole blocking layer, N-[3- (trimethoxysily)propyl]ethylenediamine grafted onto zinc oxide (ZnO/PEDA-TMS), was developed for inverted polymer light-emitting diodes (PLEDs). PEDA-TMS induced a strong dipole directed towards ZnO, as enhanced by vacuum energy level shifts of ultra-violet photoelectron spectroscopy observations, reducing the barrier height between ZnO and the emissive layer. The effect of annealing ZnO on the performance of PLEDs was analyzed using an electron-only device and capacitance-voltage (C-V) characterization. With 300 ℃ annealing treatment, ZnO provided good electron injection and blocked holes, which enhanced recombination of electrons and holes. The eletroluminescence efficiency of an inverted PLED with a ZnO/PEDA-TMS layer is similar to that of a conventional device. In addition, the electron injection mechanism of the inverted device can be explained by C-V behaviors,

which are correlated with the threshold voltage and turn-on voltage.
