A Simple Approach to Fabrication of Highly Efficient Electrolyte-Gated Organic Transistors by Phase Microsegregation of 2,7-Dioctyl [1]benzothieno[3,2-b]benzothiophene and Polystyrene Mixtures

Abstract

Electrolyte-gated organic transistors represent a promising platform for the design of fluid biosensors. The paper presents a simple and easily scalable approach to the manufacture of high-performance stable electrolyte-gated organic transistors with reproducible electrical characteristics, based on phase microsegregation in mixtures of an organic semiconductor, 2,7-dioctyl[1]benzothieno[3,2-b]benzothiophene, with a dielectric polymer, polystyrene.
