Abstract
The electronic and geometric structures of poly [3-(4-octylphenyl)thio phene] have been studied by X-ray and ultraviolet photoelectron spectr oscopy (XPS and UPS, respectively). Thermochromic effects, and new cha rge induced states generated by potassium doping, have been observed b y direct UPS measurements. The experimental results are in very good a greement with the results of theoretical quantum chemical calculations performed with the Austin Model 1 semi-empirical model and the valenc e-effective Hamiltonian pseudo-potential model.
