properties. Compounds with 2′-naphthyl and 2′-anthracyl peripheral substituents were found to have poor solubility, and were not explored in detail. However, compounds bearing 9′-anthracyl peripheral substituents exhibited better solubility, and a series of these compounds containing straight-chain and branched substituents were prepared and analyzed. These compounds were found to undergo two oxidations at
已经合成,表征和评估了一系列2,6-二芳基乙炔基-9,10-二烷氧基蒽的形态和电光性质。发现具有2'-萘基和2'-蒽基周边取代基的化合物具有较差的溶解性,因此没有详细探讨。然而,带有9'-蒽基周边取代基的化合物表现出更好的溶解性,并且制备并分析了一系列这些含有直链和支链取代基的化合物。发现这些化合物相对于Fc / Fc +参比在+0.57 V和+0.76 V下经历两次氧化。化合物以λ开始出现吸收510 nm 基于此,这些化合物的平均溶液相HOMO-LUMO能量分别估计为-5.37 eV和-2.94 eV。这些化合物表现出荧光行为,在505 nm处具有最大发射。己氧基和异丁氧基取代基最适合形成大晶体,并且对这两种化合物的晶体学研究显示,人字形排列具有一维pi堆积。
