1,3-Bis(5-bromothiophen-2-yl)-5,7-bis(2-ethylhexyl)benzo[1,2-c:4,5-c']dithiophene-4,8-dione, or BDD, is an electron deficient building block which can be used for the synthesis of low band-gap polymer semiconductors such as PBDB-T (PCE12). With two side-branched side chains, the structure is more soluble and more easily processable for device fabrications. | [Odor]
