Abstract

Three types of naphthodifurans (NDFs) have been designed as active organic materials in organic field-effect transistors (OFETs), and one of them, naphtho[2,1-b:6,5-b′]difuran, has been found to show an excellent OFET mobility of up to 3.6 cm2 V−1 s−1. Based on the crystal-packing structure and theoretical analyses, we attribute the high carrier mobility of the NDF derivatives to large intermolecular interactions and small reorganization energies. The NDF compounds show very high thermal and electrochemical stability. Together with some previous studies, the present study indicates that fused furan compounds show a performance that is equal to or better than that of the corresponding thiophene compounds.

Naphthodifurans were found to show an excellent OFET mobility of up to 3.6 cm2 V−1 s−1. We attribute the high carrier mobility to large intermolecular interactions and small reorganization energies. These studies demonstrate that fused furan compounds rival the thiophene counterparts. Fullsize Image
