Two 1,4,8,11-tetraalkyl-6,13-diphenylpentacenes were prepared. X-ray analysis revealed that the methyl derivative had a herringbone arrangement with π-overlap, while the propyl derivative had a slipped-parallel structure without π-overlap. The solid-state order reflected UV–vis absorption spectra in the solid state.
制备了两种1,4,8,11-四烷基-6,13-二苯基
并五苯化合物。X射线分析显示,甲基衍
生物具有π重叠的人字形排列,而丙基衍
生物则具有无π重叠的滑移平行结构。固态的有序性在固态的紫外-可见吸收光谱中得到了体现。
