Abstract Structural, optical and electrochemical properties of 4-amino-3-mercapto-6-(2-(2-thienyl)vinyl)-1,2,4-triazin-5(4H)-one donor (AMT) in powder and thin film forms are studied. The thermogravimetric curves (TGA and DTA) of AMT solid powder are performed for recognizing its thermal stability and thermal degradation kinetics. Integral method using Coats– Redfern and Horowitz–Metzger equations are applied in the dynamic thermal data analysis. The electrochemical reduction and oxidation potential of AMT organic material are investigated. AMT solid powder are characterized by means of optically diffused reflectance spectroscopy (DRS) based on the Kubelka–Munk model. Field emission scanning electron microscope image is characterized by the formation of nanostructure shape with average particle size 70 nm. The optical features of the AMT organic thin films are characterized by UV–Vis–NIR spectroscopy, Photoluminescence spectroscopy (PL) and Fourier transform infrared (FT-IR) spectroscopy. The optical properties such as absorption coefficient, optical gaps, refractive index, single effective oscillator energy (Eo) and dispersion energy (Ed) of the AMT organic thin films are estimated.

Organics thin films are among the most fundamental large class of materials with promising applications for electronic and photonic devices. Organic molecules composed of π-conjugated backbones have extremely rich and tailorable optoelectronic properties such as light harvesting and photoluminescence. They are already commercially applied for a wide range of applications including flexible electronic devices, optical displays and logic circuits. M
