Used in organic electronics as a hole-transport or emissive layer material in OLED devices due to its extended π-conjugated structure and thermal stability. The thiophene-quinoxaline backbone enhances charge carrier mobility, while the urea side chain improves film-forming properties and solubility in organic solvents. Shows potential in light-emitting diodes and as a host matrix for phosphorescent dopants. Also investigated for use in fluorescent sensors owing to its tunable emission properties in response to environmental changes.
