6,6-Dibromoindigo is a synthetic derivative of indigo used as a high-performance organic semiconductor in flexible electronics and thin-film transistors. Its strong intermolecular interactions and thermal stability enhance charge carrier mobility, making it suitable for organic field-effect transistors (OFETs). It is also investigated in photovoltaic cells due to its light absorption properties in the visible range. Additionally, it shows potential in biocompatible electronic devices because of its structure derived from natural indigo and low toxicity. It serves as a synthetic dye providing deep blue or purple hues with enhanced light and wash fastness, applicable in textiles, research, and specialty colorants.
