Bithiophene derivate, BT-C12-2Br
Commonly used for the synthesis of polymer semiconductors PBTTT-C12 and PQT12
BT-C12-2Br, or 5,5′-Dibromo-4,4′-didodecyl-2,2′-bithiophene, is a bithiophene derivate with unbranched dodecyl alkyl (C12) side chains. Dodecyl alkyl chains can not only enhance solubility of the targeted semiconducting polymers, but also promote film morphology with better intermolecular packing and π–π stacking.
BT-C12-2Br has been widely used for the synthesis of polymer semiconductors PBTTT-C12 and PQT12. These can be used to create organic field-effect transistors (OFETs) with high charge mobilities.
