In this study, we designed dialkoxyanthracene as donor units. The anthracene is fused and planar aromatic with rich electrons that induced efficient intermolecular π– π interaction, resulting in good charge mobility. Furthermore, the introduction of dialkoxy group on the 9,10-position of anthracene can increase solubility as well as electron density due to the dialkoxy side chains. Replacement of alkoxynaphthalene with alkoxyanthracene is a promising strategy to increase the diversity of modification of the molecule and electronic structures, which can lead to the development of good organic semiconducting material due to the extended p-conjugation. Here, we report on the synthesis and characterization of new copolymers, that are composed of dialkoxyanthracene as donor and benzothiadiazole as acceptor (ODA-BT), and dialkoxyanthracene as donor and thiophene benzothiadiazole thiophene as acceptor (ODA-TBT) for organic photovoltaic cells. |
