Current–voltage characteristics of PTSA/I2 doped poly(4 vinyl pyridine)

The electrical conductivity and optical properties of the bis-diethylaminokumarin have been investigated. The electrical conductivity of the compound exhibited three-dimensional hopping conduction in the temperature range 295−321 K. The compound shows typical semiconductor property and its semiconducting property results from delocalization of the π-electrons in the structure. To determine the optical band gap of the compound, an optical absorption study was made in the wavelength range 250−600 nm. The optical study revealed that the optical transition is the allowed indirect one. The electronic parameters such as electrical conductivity at room temperature σ 25 , activation energy E, and optical band gap Eg , of the compound are 1.46 · 10 −5 S/cm, 0.42 eV and 2.46 eV, respectively. These values are in agreement with electronic parameters of organic semiconductors.
