Quinoxaline-based semiconducting materials are currently of high interest in the field of organic photovoltaics. The number of structural variations employed has been, however, quite limited to date. In this paper we report on the synthesis of a series of quinoxaline monomers and triads with improved optical features. This was achieved by using conjugated linkers, i.e. ethenyl, butadienyl and/or aryl groups, to graft the solubilizing alkyl side chains onto the central quinoxaline core. The influence of the appended groups on the light-harvesting properties of the materials is briefly discussed.
喹喘啉基半导体材料目前在有机光伏领域备受关注。然而,迄今为止所采用的结构变化种类相当有限。本文报道了一系列具有改善光学特性的喹喘啉单体和三体的合成。通过使用共轭连接体(即乙烯基、丁二烯基和/或芳基)将增溶的烷基侧链嫁接到中心喹喘啉核心上,实现了这一目标。简要讨论了所附加基团对材料的光捕获特性的影响。
