Solid-state NMR of Organic Electronics

Abstract

Organic materials that exhibit high charge conductivities have potential uses in a number of electronics application areas, such as photovoltaics and flat panel displays and what once was a perpetual “on the horizon” class of materials, organic electronics are finding many real-world uses in a number of flexible electronics applications such as wearable sensors. However, regardless of the applied technology, precise knowledge of the morphologies of the organic molecules that comprise the active material are critical to optimizing the functionality. Solid-state NMR is a powerful analytical tool for deciphering local structures in complex morphologies and measuring molecular dynamics in dynamically heterogeneous materials. In this review, we cover recent solid-state NMR works that have focused on organic electronics materials such as polythiophenes, polyphenylene vinylenes, polyfluorenes, and a number of donor–acceptor polymers with applications in organic electronics, namely organic thin film transistors, organic light emitting diodes, and organic photovoltaics.
