Cas 165617-59-4 For Oled & Opv Research

4,8-Dibromobenzo[1,2-c:4,5-c'']bis([1,2,5]thiadiazole) (CAS: 165617-59-4) is a highly conjugated sulfur- and nitrogen-rich heteroaromatic compound widely used as a functional intermediate in organic electronic materials. The molecule features a rigid, fused bis(thiadiazole) core substituted with two bromine atoms, providing both strong electron-withdrawing character and excellent reactivity for further functionalization. This compound is typically supplied as a brownish-red powder with a minimum purity of 95%, making it suitable for advanced research and material development. Owing to its extended p-conjugated system and heteroatom-rich framework, it is particularly valuable in the design of electron-accepting units for optoelectronic applications. In materials science and organic electronics, 4,8-dibromobenzo[1,2-c:4,5-c'']bis([1,2,5]thiadiazole) is frequently employed as a key building block for the synthesis of small molecules and conjugated polymers used in OLEDs, organic photovoltaics (OPVs), organic field-effect transistors (OFETs), and photodetectors. The bromine substituents enable efficient cross-coupling reactions such as Suzuki, Stille, and Negishi couplings, allowing precise tuning of electronic structures and energy levels. From a research perspective, the strong electron-deficient nature of the bis(thiadiazole) core enhances charge transport and intermolecular interactions, contributing to improved thermal stability and optoelectronic performance in final materials. As a result, this compound is of particular interest in the development of next-generation semiconducting and photoactive systems.
