In this study, 4-phenylthiazol-2-yl-(phenylhydrazono) acetonitrile (PTPA) azo dye was synthesized and studied from optical and electrical point of view. The tautomerization phenomenon of the PTPA dye was clarified using one- dimensional (1D) and two- dimensional (2D) nuclear magnetic resonance (1HNMR and 13C NMR), absorbance (UV-Vis), emission, and infrared spectroscopy (FT-IR). X-ray diffraction (XRD) evaluations indicated that PTPA in powder and thin films crystallizes in a monoclinic system structure with nonostructural characteristics. Spectrophotometric measurements of absorbance A (λ), transmittance T (λ), and reflectance R (λ) at normal incidence light in the wavelength range 200–2500 nm were used to determine optical band gap, extinction coefficient, k, and refractive index, n. Also, non-linear optical parameters such as the third order non-linear susceptibility, χ(3) and nonlinear refractive index, n(2), of PTPA were revealed an awe-inspiring switching behavior, implying the possibility of using PTPA in optical switching systems. Finally, the electrical conductivity of the PTPA was raised with rising temperature, indicating that it is a typical organic semiconductor. Mott’s parameters were determined and discussed at low temperature. Thus, PTPA is a promising organic semiconductor with broad utility potential in organic electronics such as organic light-emitting diodes (OLEDs).
