[structure: see text] We report the synthesis of a series of crystalline acenedithiophenes with up to seven linearly fused rings and silylethynyl substituents. These functional groups are designed to both improve solubility and enhance cofacial interactions in the solid. We discuss the crystal packing of these materials, as well as their physical properties such as oxidation potential, UV-vis absorption
[结构:见正文]我们报告了一系列具有多达七个线性稠合环和甲
硅烷基
乙炔基取代基的结晶a庚二烯
噻吩的合成。这些官能团被设计为既改善溶解度又增强固体中的界面相互作用。我们讨论了这些材料的晶体堆积,以及它们的物理性质,例如氧化电位,UV-vis吸收,荧光发射和分解途径。
