BT-C14-2Br, namely 5,5′-Dibromo-4,4′-ditetradecyl-2,2′-bithiophene, is a bithiophene derivate with unbranched tetradecyl alkyl (C14) chains. C14 side chains have tendency to self-aggregate in the mixture of solvent/non-solvent, i.e. chloroform and toluene.

BT-C14-2Br is normally used as a building block for the synthesis of PBTTT-C14.
