N2 - The synthesis and optical properties of the 5,5′,6,6′-tetraphenyl-2,2′-bi([1,3]dithiolo [4,5-b] [1,4]dithiinylidene)-2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) complex thin film were investigated by the optical characterization. The optical constants such as refractive index, extinction coefficient and absorption coefficient were determined using the transmittance T(λ) and reflectance R(λ) spectra and the refractive index dispersion was analyzed using single oscillator of Wemple-Didomenico model. The single oscillator energy E0 and the dispersion energy Ed were calculated. The effect of temperature on refractive dispersion and optical band gap Eg is also discussed. As a result, the annealing temperatures have an important effect on refractive index of thin film.
