Syntheses, spectroscopic characterization, and electrical properties of important semiconducting organic compound

This work proposes the synthesis of new azomethine by the reaction of enaminone with an appropriate aldehyde. The new compound was identified by NMR (1H and 13C), and others techniques such as: UV–Vis spectroscopy, Fourier Transform Infra-red spectroscopy (FT-IR) and X-ray diffraction (XRD). The optical data shows the synthesized azomethine exhibit low band gaps. (Eg =2.87 eV). Electrical conductivity study indicates that conductivity of product is in the range of ∼ 10−6 S/cm. So, it is evaluated that the sample is a typical organic semiconductor as its conductivity increases with increasing temperature and the electronic parameters such as activation energy and room-temperature conductivity are in the regime of semiconductors. It is also found that the dielectric constant and the dielectric loss values increase with temperature and decrease with frequencies. Furthermore, the results obtained in this pioneering study are thoughtfully discussed in the context of existing literature. This study is opening doors to potential applications in chemistry.
