The relentless pursuit of higher performance and efficiency in organic electronics, particularly in OLED (Organic Light-Emitting Diode) and OPV (Organic Photovoltaic) devices, necessitates the use of highly specialized chemical intermediates. One such critical compound is 4,7-Bis(5-bromothiophen-2-yl)benzo[c][1,2,5]selenadiazole, identified by its CAS number 534591-72-5. This article aims to provide an in-depth look at this material and its significance, guiding procurement managers and R&D scientists on where and how to buy it.

Chemical Profile and Significance

4,7-Bis(5-bromothiophen-2-yl)benzo[c][1,2,5]selenadiazole is a complex organic molecule with the molecular formula C14H6N2S2SeBr2 and a molecular weight of 505.11 g/mol. Its structure is characterized by thiophene rings substituted with bromine atoms, linked to a central benzoselenadiazole core. The presence of bromine atoms, known for their electron-withdrawing capabilities, allows for fine-tuning of the material's electronic energy levels (HOMO/LUMO). This tunability is crucial for optimizing charge injection and transport in electronic devices, as well as influencing the optical properties required for light emission or absorption.

Applications in OLED and OPV Devices

In OLED technology, this intermediate can be a precursor for developing efficient charge transport materials, especially electron transport layers (ETLs), or components of emissive molecules. Its role is to facilitate the balanced flow of electrons and holes to the emissive layer, thereby enhancing the quantum efficiency and brightness of the OLED. For OPVs, it serves as a fundamental building block for synthesizing donor-acceptor conjugated polymers or small molecules. These materials are designed to efficiently absorb sunlight and facilitate charge separation, directly impacting the power conversion efficiency of the solar cells. Therefore, for any researcher or manufacturer aiming to develop superior OLED or OPV devices, sourcing this material is a key step.
