Small Molecule/Polymer Blend Organic Transistors with Hole Mobility Exceeding 13 cm² V⁻¹ s⁻¹

Abstract

A ternary organic semiconducting blend composed of a small-molecule, a conjugated polymer, and a molecular p-dopant is developed and used in solution-processed organic transistors with hole mobility exceeding 13 cm(2) V(-1) s(-1) (see the Figure). It is shown that key to this development is the incorporation of the p-dopant and the formation of a vertically phase-separated film microstructure.
