Abstract
The effects of molecular structure on the redox properties are explored by the cyclic voltammetry, constant current potentiometry and spectroscopy using the thin films of organic electroluminescence materials of Poly(N-vinylcarbazole); PVK and 2- (4'-tert-butylphenyl) -5-(4"-bisphenyl) -1,3,4-oxadiazole; PBD. The UV/visible absorption maxima and band gap (E$\_$g/) show at 310nm (4.00eV) and 368nm (3.37eV) for FBD, 344nm (3.60eV) and 356nm (3.48eV) for PVK, respectively. The measured electrochemical ionization potential (IP) and electron affinity (EA) of these materials we 5.87 and 2.82eV for PBD, 5.80 and 3.17eV for PVK, respectively. The electrical band gaps are 3.05eV for PBD and 2.78eV for PVK, respectively. The electrical hole gap and electron gap with respect to the first rising potentials and the inflection potentials are obtained to be 0.39V and 0.41V for PBD, 0.25V and 0.28V for FVK, respectively.
