Linear‐fused naphthodithiophenes ( NDT s) are emerging building blocks in the development of new semiconducting small molecules, oligomers, and polymers. The promising nature of NDT ‐based materials as organic semiconductors has been demonstrated by superior device characteristics in organic field‐effect transistors ( OFET s) and organic photovoltaics ( OPV s) in the last few years. In particular, it is quite impressive that a power conversion efficiency as high as 8.2% has been achieved for a single‐junction OPV cell consisting of NDT ‐based semiconducting polymers and a fullerene derivative in such a short period of time. Here, we provide an overview of recent synthetic evolutions in NDT chemistry and progress in NDT ‐based materials, especially conjugated oligomers and polymers and their applications to OFET s and OPV s.
