Abstract

Poly(3-hexythiophene) (P3HT) is one of the most extensively studied polymers for applications in organic thin-film transistors. Semicrystalline P3HT is a p-type semiconductor enabling applications in the unipolar organic field-effect transistors (OFETs). Blending P3HT with small molecular compounds can enhance the mobility of charge carriers in the OFET active layer. When small molecules reveal electron conductivity and their phase separation upon crystallization in the presence of P3HT results in formation of heterojunctions, the blends can be considered candidates for active layers in the ambipolar OFETs. Regardless of unipolar or ambipolar, the charge carrier transport always depends on the inherent properties of the polymer and small molecules as well as the crystalline structure and morphology (nanostructure) of the blends. This paper is a brief review of the recent findings regarding relationships between structure and properties of the active layers of P3HT and P3HT blends-based OFETs. Herein we discuss examples of blends of P3HT with, amongst others, perylene diimide derivatives, and discuss their OFET-related properties, like charge-carrier mobility, in relation to both crystalline structure of the blend components and blend morphology. Some key issues related to morphology control by changing layer formation conditions are also indicated in this paper.
