Product Detail

Benzo[1,2-b:4,5-b']dithiophene-4,8-dione (BDT-dione), with the molecular formula C₁₀H₄O₂S₂, is a fused heterocyclic diketone compound that serves as one of the most important building blocks in the field of organic electronics. Its rigid, planar fused-ring structure, combined with two electron-withdrawing carbonyl groups, gives the molecule strong electron-accepting character and excellent π-stacking ability, making it an indispensable intermediate for constructing high-performance conjugated polymers and small molecules.

In organic photovoltaic (OPV) research, BDT-dione is widely used as a key monomer for the synthesis of donor-acceptor (D-A) copolymers. When incorporated into the polymer backbone, it enhances molecular planarity, extends absorption into the near-infrared region, and improves charge transport properties, all of which contribute to higher power conversion efficiency in organic solar cells. It is also employed in the development of non-fullerene acceptors and ternary blend systems, where its electron-deficient core enables fine-tuning of energy levels and morphology.

Beyond photovoltaics, BDT-dione derivatives are utilized in organic field-effect transistors (OFETs), organic photodetectors, electrochromic materials, and perovskite solar cell interfacial layers. The compound is also a valuable synthetic platform for introducing side-chain engineering and functionalization, allowing researchers to tailor solubility, aggregation behavior, and film morphology for specific device requirements.

Quality assurance: our BDT-dione is synthesized and purified under strict process control, with consistent purity verified by HPLC analysis and structure confirmed by NMR. Each batch is tested before shipment and accompanied by a Certificate of Analysis. The product is packaged under inert conditions to preserve stability and performance.

Storage and handling: store in a cool, dry, and dark environment, preferably under inert atmosphere, with the container kept tightly sealed. Avoid prolonged exposure to light, moisture, and high temperature. Handle in a well-ventilated area using standard protective equipment such as gloves and safety goggles, and avoid inhalation of dust.

With its proven value in organic photovoltaics, organic electronics, and advanced materials research, Benzo[1,2-b:4,5-b']dithiophene-4,8-dione is a reliable choice for research institutions, material suppliers, and device manufacturers worldwide.
