Abstract

The electron acceptor building block N,N′-dialkoxynaphthalenediimide (NDIO) has been, for the first time, used to develop an n-type polymer semiconductor, P(NDIO2OD-T). The polymer exhibits unipolar electron charge transport with an electron mobility of up to 5.4 × 10⁻³ cm² V⁻¹ s⁻¹ in organic thin-film transistors (OTFTs) and shows good air-stability. When it is used as the acceptor in all-polymer solar cells (all-PSCs), a PCE of up to 3.25% is achieved. The performances of the OTFTs and all-PSCs based on this polymer have improved compared to its N,N′-dialkyl-substituted analogue.
