A series of 6,12-bis[(trialkylsilyl)ethynyl]indeno[1,2-b]fluorene-5,11-diones has been synthesized. X-ray crystallographic analysis of these compounds reveals that triisopropylsilyl (TIPS) substitution on the alkyne terminus affords the largest number of intermolecular π−π interactions in the solid state. Conversely, use of trialkylsilyl groups smaller or larger than TIPS furnishes a variety of crystal-packing
合成了一系列的6,12-双[(三烷基甲硅烷基)乙炔基]茚并[1,2 - b ]芴-5,11-二酮。这些化合物的X射线晶体学分析表明,炔烃末端上的三异丙基甲硅烷基(TIPS)取代提供了固态的最大分子间π-π相互作用。相反,使用小于或大于TIPS的三烷基甲硅烷基可提供各种包含较少π-π相互作用的晶体堆积基序。电化学和光物理数据表明,这些分子是极好的电子接受材料。

Redox‐controlled dimerization of tetrathiafulvalene (TTF) derivatives is an important tool for achieving reversible assemblies. Herein, the synthesis and characterization of indacene–TTF hybrids, in which the central core is fused to naphtho or benzothieno units, are reported. The orientation of these units has a strong influence on the redox properties, with regard to the number of electrons involved
