A new class of fullyconjugated indenofluorenes has been synthesized and confirmed by solid-state structure analysis. These indeno[2,1-c]fluorene molecules, containing an antiaromatic as-indacene core (in red), possess high electron affinities and show a broad absorption that reaches into the near-IR region of the electromagnetic spectrum. All of the featured compounds reversibly accept up to two electrons
已经合成了一类新的完全共轭的茚并芴,并通过固态结构分析得到了证实。这些茚并[2,1- c ^ ]芴分子,含有反芳香如-indacene芯(红色),具有高电子亲合性,并显示出宽的吸收到达进入电磁波谱的近红外区域。所有具有特征的化合物可逆地接受多达两个电子。它们的电子特性使这类化合物吸引有机电子设备中的应用。

A set of fully‐conjugated indenofluorenes has been synthesized and confirmed by solid‐state structure analysis. The indeno[2,1‐c]fluorenes and their benzo‐fused analogues all contain the antiaromatic as‐indacene core.

合成了一组完全共轭的茚并芴,并通过固态结构分析进行了确认。茚并[ 2,1– c ]芴及其苯并稠合类似物均含有抗芳烃作为茚满并烯的核心。这些分子具有很高的电子亲和力,并显示出广泛的吸收能力,可吸收到电磁光谱的近红外区域。如循环伏安法所揭示的,所有具有特征的化合物最多可逆地接受两个电子。使用NICS-XY扫描计算对分子的亲和性进行分析表明,尽管as-茚并二烯核的顺性性低于s-茚并二烯,但苯并[a]环化进一步降低了核的抗芳香性。的反芳香强度为还可以通过外圈上其他芳烃的融合位置来调节ind-茚并茂的核心。

Described herein is an alternative synthetic approach for conjugatedindeno[2,1-c]fluorene, including the experimental and theoretical investigations of a tetraradicaloid s-indaceno[2,1-c:6,5-c′]difluorene that belongs to the rarely explored indacenodifluorene family containing 4n + 2 monocyclic conjugated π-electrons. Expedient synthesis, broad absorption reaching 1150 nm, and small HOMO–LUMO energy
