Phenanthrylene-butadiynylene and Phenanthrylene-thienylene Macrocycles: Synthesis, Structure, and Properties

A series of macrocycles consisting of 9,10-substituted phenanthrenes connected by butadiynylene linkers in positions 3 and 6 has been described as well as their transformation into the corresponding phenanthrylene-thienylene macrocycles. Structure and properties of the macrocycles, such as self-association in solution and optical and electrochemical properties, were studied and reported in a comparative manner with respect to the effects of the different sizes and shapes of the macrocycles and the character and length of their side chains.本研究报道了一类由3,6位通过丁二炔连接臂（butadiynylene linkers）相连的9,10-取代菲（9,10-substituted phenanthrenes）构成的大环化合物（macrocycles），以及它们向对应菲撑-噻吩撑大环化合物（phenanthrylene-thienylene macrocycles）的转化反应。针对该类大环化合物的不同尺寸、形貌以及侧链的性质与长度所产生的影响，本研究以对比研究的方式，对其结构与性质（包括溶液中的自聚集行为、光学及电化学性质）开展了系统探究并予以报道。
