Improved Field-Effect Transistor Performance of a Benzotrithiophene Polymer through Ketal Cleavage in the Solid State (vol 5, pg 1806, 2013)

Abstract

A benzotrithiophene polymer with a new thermally cleavable ketal substituent is reported and it is shown how this functional group can be used to facilitate solvent processing and subsequently how it can be removed by a thermal annealing process to generate a tightly packed and structurally ordered thin film with significantly improved field-effect transistor properties
