Poly(naphthalene diimide) vinylene: solid state red emission and semiconducting properties for transistors

Abstract

In this work, a conjugated polymer PNV is developed, linking naphthalene diimide with a vinyl linkage. Owing to the C–H⋯O hydrogen bond between the carbonyl and the vinyl, PNV exhibits a high red emission with a quantum yield of 33.4% in the solid state while it shows n-type properties with an electron mobility up to 1.5 × 10⁻³ cm² V⁻¹ s⁻¹ in organic field effect transistors, simultaneously.
