A general methodology has been proposed for the straightforward access to 4,8-functionalized benzo[1,2-b:4,5-b′]dithiophenes (BDTs) via Pd mediated coupling reactions including Suzuki-Sonogashira coupling and carbon-sulfur bond formation reactions. This versatile platform can be used to construct a library of BDT core centred conjugated systems, featuring large fused-ring structure and good charge mobility, where a hole mobility of 0.061 cm2 V -1 s-1 is demonstrated. With the energy level fine-tuned with functionalization, the charge transporting BDTs show great potential for donor-acceptor polymers. This journal is the Partner Organisations 2014.
