We report a new synthetic route to 5,11-disubstituted indeno[1,2-b]fluorene-6,12-diones that is amenable to larger scale reactions, allowing for the preparation of gram amounts of material. With this new methodology, we explored the effects on crystal packing morphology for the indeno[1,2-b]fluorene-6,12-diones by varying the substituents on the silylethynyl groups.

5,11-二乙炔化茚并[1,2-b]芴-6,12-二酮的可扩展合成及其固态堆积的探索。

我们报告了一种新的 5,11-二取代茚并 [1,2-b] 芴-6,12-二酮合成路线，该路线适用于更大规模的反应，允许制备克量的材料。使用这种新方法，我们通过改变甲硅烷基乙炔基上的取代基，探索了对茚并 [1,2-b] 芴-6,12-二酮的晶体堆积形态的影响。
