For product formulators and R&D scientists in the organic electronics industry, a deep understanding of material properties is fundamental to successful device development. DACT-II (CAS 1613074-59-1), a key player in the realm of Thermally Activated Delayed Fluorescence (TADF) emitters, is highly sought after for its performance characteristics in green OLED applications. This article provides an in-depth look at the critical properties of DACT-II, empowering formulators to make informed decisions when they seek to buy this advanced material. As a specialized manufacturer and supplier, we are dedicated to providing comprehensive technical data to support your innovation.

At the core of DACT-II’s exceptional performance are its well-defined electronic properties. The Highest Occupied Molecular Orbital (HOMO) level is reported at 5.50 eV, and the Lowest Unoccupied Molecular Orbital (LUMO) level at 3.30 eV. These values are crucial for optimizing charge injection and transport within the OLED device stack, ensuring efficient recombination and light emission. Understanding these energy levels allows formulators to design balanced device architectures that maximize the contribution of DACT-II as a green emitter. When you buy DACT-II from a reputable supplier, you receive materials with these precise, verified specifications.

The purity of DACT-II is another critical determinant of its performance. Our DACT-II is processed using sublimation techniques, achieving a purity level exceeding 99.0% as confirmed by High-Performance Liquid Chromatography (HPLC). High purity minimizes non-radiative decay pathways and charge trapping, thereby enhancing both the efficiency and the operational lifetime of the OLED device. For formulators and procurement specialists, sourcing from a manufacturer that guarantees such high purity is vital for product reliability. We stand as a trusted supplier committed to delivering consistent, high-quality DACT-II for your critical applications.

Beyond its electronic properties and purity, the thermal stability of DACT-II is noteworthy. With a glass transition temperature (Tg) reported between 151-159°C (bulk sample) and 192-197°C (in film), DACT-II offers robust thermal resilience. This property is essential for maintaining device integrity during operation and manufacturing processes, where elevated temperatures can be encountered. Good thermal stability contributes to longer device lifetimes and resistance to morphological changes, making DACT-II a superior choice for demanding display applications. Consider our competitive pricing when you plan your next purchase.

DACT-II’s molecular structure, a synergy of electron-deficient diphenyltriazine and electron-rich diphenylaminocarbazole units, is finely tuned to achieve a small energy gap between its singlet and triplet excited states (ΔEST). This characteristic is fundamental to its ability to harness triplet excitons via reverse intersystem crossing (RISC), a key mechanism for TADF emitters. This efficient conversion directly translates to high internal quantum efficiencies, enabling brighter and more energy-efficient OLEDs. As a manufacturer and supplier of these advanced materials, we provide the building blocks for the next generation of displays.

In summary, DACT-II is a meticulously engineered TADF green emitter with a profile of outstanding properties, including optimized HOMO/LUMO levels, exceptional purity, and robust thermal stability. For OLED formulators and R&D professionals, understanding and leveraging these characteristics is key to unlocking superior device performance.
