Paper Abstract

Syntheses, characterizations, and applications to organic field-effect transistors (OFETs) of four isomeric naphthodithiophenes (NDTs) are reported. The NDT cores are utilized to both small-molecular organic semiconductors for vapor-processed OFETs and polymer semiconductors for solution processed OFETs. For the vapor-processed OFETs, the linear-shaped NDT gives the best material showing mobility of up to 1.5 cm2 V-1 s-1, whereas for the polymer-based solution-processed OFETs, the angular-shaped NDT gives better results with mobility as high as 0.77 cm2 V-1 s-1. To understand the different trends in the mobility of the two systems, the packing structure and intermolecular orbital interaction are studied.
