Heterocyclic compounds are essential in the material sciences due to their distinctive structure, which providesthemwithvarious adjustable electrical and physicochemical properties. Researchers develop materials with specific characteristicsforvariousinnovative uses by modifying the type and positioning of heteroatoms. In material science, heterocyclic compounds are usedinseveralapplications, such as fluorescent markers for imaging and diagnostics, polymers and copolymers for their structural andelectricalcharacteristics, and dyes and pigments for their coloring capabilities. They can also be used as corrosion inhibitors, developers,antioxidants, and parts of photovoltaic cells and light-emitting diodes (LEDs) because of their special structural andchemicalcharacteristics. Keywords: Heterocyclic compounds, organic electronics, dyes, pigments, polymers, corrosion inhibitors
