The remarkable advancements in organic light-emitting diode (OLED) technology are fundamentally driven by the sophisticated design and synthesis of organic semiconductor materials. At the heart of these materials are organic intermediates, chemical compounds that serve as the building blocks for advanced functional molecules. DACT-II, bearing the CAS number 1613074-59-1, is a prime example of such a critical intermediate. Typically appearing as a yellow powder, DACT-II is recognized for its role in developing high-performance Thermally Activated Delayed Fluorescence (TADF) emitters, crucial for enhancing the efficiency and brightness of OLED displays and lighting. Understanding its chemical structure and properties is vital for researchers and manufacturers seeking to leverage its potential.

The molecular formula of DACT-II is C57H40N6, with a corresponding molecular weight of approximately 808.99 g/mol. This complex structure is deliberately engineered to facilitate the optoelectronic processes necessary for efficient fluorescence. It typically consists of electron-rich carbazole units and electron-deficient triazine units, interconnected via a phenyl linker. This specific arrangement allows for a small energy difference between the lowest singlet excited state (S1) and the lowest triplet excited state (T1), which is the defining characteristic of TADF materials. The ability to efficiently convert triplet excitons back into singlet excitons via reverse intersystem crossing (RISC) is what enables TADF emitters to achieve near 100% internal quantum efficiency, a significant leap from conventional fluorescent materials. Researchers looking to buy DACT-II often seek this precise structural configuration for their synthesis of novel emitters.

Key physical and chemical properties of DACT-II are critical for its effective use. Its appearance as a yellow powder is standard for many organic intermediates used in electronics. Furthermore, its solubility in common organic solvents such as chloroform and tetrahydrofuran (THF) is highly advantageous for solution-based processing and chemical synthesis. This solubility profile allows for straightforward integration into various manufacturing workflows. For optimal performance and longevity, DACT-II requires specific storage conditions, typically at 25°C under an inert atmosphere (like nitrogen), to prevent degradation and maintain its high purity, often exceeding 98% by HPLC.
