We report the synthesis, characterization, and OFET and OPV properties of a series of novel naphthodithiophene (NDT3)-based donor-acceptor semiconducting polymers. A striking feature of the present polymers is the very close π-π stacking of 3.5 Å, most likely as a result of the large π system and the D-A system in the polymer backbone. PNDT3NTz-DT, in particular, is found to be one of the few examples of versatile polymers that exhibit both the field-effect mobility of ∼0.5 cm/(V s) and the PCE of ∼5%. These results indicate that NDT3 is a promising versatile core unit for semiconducting polymers and that the use of highly π-extended heteroarenes as both the donor and the acceptor unit is a promising design strategy to develop high performance polymers.
我们报道了一系列基于新型萘并二噻吩（NDT3）的供体-受体半导体聚合物的合成、表征以及场效应晶体管（OFET）和有机光伏电池（OPV）性能。当前聚合物的一个显著特征是具有非常紧密的3.5 Å的π-π堆积，这很可能是聚合物主链中较大的π体系和给体-受体（D-A）体系导致的。特别是，PNDT3NTz-DT被发现是少数兼具约0.5 cm/(V s)的场效应迁移率和约5%的功率转换效率（PCE）的通用聚合物实例之一。这些结果表明，NDT3是用于半导体聚合物的一种有前景的通用核心单元，并且使用高度π扩展的杂芳烃作为供体和受体单元是开发高性能聚合物的一种有前景的设计策略。
