Bridged oligophenylenes are very important organic semiconductors (OSCs) in organic electronics (OE). The fluorene unit, which is a bridged biphenyl, is the spearhead of this class of materials and has, over the last 20 years, led to fantastic breakthroughs in organic light-emitting diodes. Dihydroindenofluorenes belong to the family of bridged terphenyls and can be viewed as the fusion of a fluorene unit with an indene fragment. Dihydroindenofluorenes have also appeared as very promising building blocks for OE applications. In the dihydroindenofluorene family, there are five positional isomers, with three different phenyl linkages (para/meta/ortho) and two different ring bridge arrangements (anti/syn). We have focused on the concept of positional isomerism. Indeed, the structural differences of the dihydroindenofluorenyl cores lead to unusual electronic properties, which our group has described since 2006, thanks to the five dispirofluorene–indenofluorene positional isomers (dihydroindenofluorenes substituted on the bridges by fluorenyl units).

二氢茚芴位置异构体
桥接的低聚亚苯基是有机电子(OE)中非常重要的有机半导体(OSC)。芴单元是桥联苯,是此类材料的先驱,在过去的20年中,已导致有机发光二极管取得了惊人的突破。二氢茚并芴属于桥联的三联苯家族,可以看作是芴单元与茚片段的融合。二氢茚并芴也已成为OE应用中非常有前途的构建基块。在dihydroindenofluorene家族,有五个位置异构体,用三种不同的苯基的键(对位/间位/邻位)和两个不同的环电桥装置(反/顺)。我们专注于位置异构的概念。实际上,由于五个双螺芴-茚芴位置异构体(桥上被芴基单元取代的二氢茚芴),二氢茚并芴基核的结构差异导致了异常的电子性能,自2006年以来,我们的研究小组就对它们进行了描述。
