Used as a high-performance optical brightener in specialty polymers and coatings, T2T exhibits exceptional UV absorption and thermal stability. It is particularly effective in polycarbonate and acrylic formulations where long-term clarity and resistance to yellowing are critical. Due to its large conjugated structure, it acts as an efficient triplet-triplet annihilation (TTA) sensitizer in photon upconversion systems, making it valuable in advanced solar cell research and photocatalytic applications. T2T is also employed in OLED materials to enhance electron transport and improve device efficiency. Its rigid, star-shaped architecture contributes to high glass transition temperatures in polymer blends, supporting use in high-temperature engineering plastics.
