Five congeners of [n]cyclo-3,6-phenanthrenylene with 3, 4, 5, 7, and 8 panels were obtained from one-pot macrocyclization of dibromophenanthrene, and their crystal structures with diverse molecular shapes were revealed by X-ray crystallography. The compounds, except the four-panel congener, were highly fluorescent in solution, with quantum yields up to 85 %. The least fluorescent four-panel congener

溴菲的大环化反应获得了具有3、4、5、7和8个面板的5个同族的[ n ]环3,6-
菲撑,并通过X射线晶体学揭示了它们具有不同分子形状的晶体结构。除四板同源物外,这些化合物在溶液中均具有高荧光性,量子产率高达85%。与单体
菲相比,荧光最少的四板同类物在吸收光谱上的变化最小,这为荧光大环化合物提供了有趣的结构-活性关系,以指导未来的研究。
