Abstract
We have already reported the syntheses of naphthodithiophenes (NDTs) being potential as new core structures for organic semiconductors. In this study, naphthodifurans (NDFs) and naphthodiselenophenes (NDSs) were synthesized and evaluated as organic semiconductors. Similar to the DPh-NDT-based OFETs, DPh-NDF and DPh-NDS-based devices showed typical FET characteristics with FET mobilities of up to 0.6 and 1.0 cm2/Vs, respectively, indicated that both NDF and NDS are promising core structure for organic semiconductors. Furthermore, DPh-NDXs acted as a p-type material in the bilayer organic photovoltaic devices (OPVs) combined with C60. Among these OPVs, the DPh-NDF based one showed the best performances with PCE of up to 1.3%. In the contribution, similarity and differences of the OFET- and OPV- characteristics of these naphthodichalcogenophenes (NDXs)-based devices will be discussed in terms of their optical/electrochemical properties and thin film structures in the solid state.
