Diseleno[3,2‐b:2′,3′‐d]selenophenes: Diseleno[3,2‐b:2′,3′‐d]selenophene‐Containing High‐Mobility Conjugated Polymer for Organic Field‐Effect Transistors (Adv. Sci. 13/2019)

Abstract

In article number 1900245, Martin Heeney, Dong‐Yu Kim, and co‐workers describe an organic field‐effect transistor featuring a semiconducting polymer, PDSSTV, in its channel layer. The newly developed unit of three‐fused selenophenes enables the polymer to have a strong intermolecular interaction caused by large and polarizable orbitals of selenium. The PDSSTV demonstrates its maximum hole mobility of 2.1 cm² V⁻¹ s⁻¹ at a low operating voltage, –30 V.
