Description

In1703, 4,8-Bis(5-(Dodecylthio)Thiophen-2-Yl)Benzo[1,2-B:4,5-B']Dithiophene is a high-performance organic semiconductor material belonging to the benzo[1,2-b:4,5-b']dithiophene (BDT) family. This compound matters for its excellent charge-carrier mobility and tunable electronic properties, making it a critical component in advanced optoelectronic devices. It is primarily needed by researchers and manufacturers in the organic electronics sector, particularly for developing next-generation organic photovoltaics (OPVs) and organic field-effect transistors (OFETs).

Application

• As a p-type donor material in the active layer of bulk-heterojunction organic solar cells (OSCs).
• As a key semiconducting component in the fabrication of high-mobility organic field-effect transistors (OFETs).
• As a building block (monomer) for synthesizing conjugated polymers with tailored energy levels for photovoltaics.
• In research and development of novel organic electronic materials and device architectures.
• For use in perovskite solar cells as a hole-transporting or interfacial layer material.
• As a model compound for studying structure-property relationships in thiophene-based organic semiconductors.
