and the thermal stability of the acenaphtho[c]phosphole π‐systems are finely tunable with the α‐aryl substituents. All the PO and PS derivatives exhibited high stability in their electrochemically reduced state. To use this class of arene‐fused phosphole π‐systems as n‐type semiconducting materials, we evaluated device performances of the bulk heterojunction organic photovoltaics (OPV) that consist
建立了一种发散合成α,α'-二芳基萘并[1,2- c ]磷脂P-氧化物的方法。α,α'-dibromoacenaphtho [ C ^ ]磷杂环P氧化物,将其通过制备的Ti II介导的1,8-双(三甲基硅乙炔)萘的环化,进行了具有的Stille三种不同aryltributylstannanes的耦合,得到α, α'-diarylacenaphtho [ C ^ ]磷杂环P -oxides在中度至良好的产率。X射线晶体学分析和UV / Vis吸收/荧光测量表明,ph的π共轭度,堆积基序,电子接受能力和热稳定性[ c]]磷π系统可以与α-芳基取代基很好地调节。所有的PO和PS衍生物在电化学还原状态下均表现出高稳定性。要将此类芳烃融合的π系统用作n型半导体材料,我们评估了由聚(3-己基噻吩),茚-C 70双加合物和阴极缓冲层。所述diarylacenaphtho [插入Ç ]磷杂环P -ox
