The synthesis of ethyne-linked porphyrin nanorings has been achieved by template-directed Sonogashira coupling. The cyclic hexamer and octamer are predicted by density functional theory to adopt low symmetry conformations, due to dihedral twists between neighboring porphyrin units, but their symmetries are effectively D6h and D8h, respectively, in solution by 1H NMR. The fluorescence spectra indicate that the singlet excited states of these nanorings are highly delocalized.

单乙炔连接卟啉纳米环
乙炔连接的卟啉纳米环的合成已通过模板导向的Sonogashira偶联实现。密度泛函理论预测环状六聚体和八聚体由于相邻卟啉单元之间的二面体扭曲而采用低对称构象，但通过1 H NMR ，它们的对称性分别为D 6h和D 8h。荧光光谱表明这些纳米环的单线激发态高度离域。
