This study strategically prepared two pairs of isomers of heptagon-embedded helical arenes (3/6 and 10/13) and identified the molecular structures of 3 and 13 using single crystal X-ray diffraction analysis. The physical properties of 3, 6, 10, and 13 were comparatively investigated, and the results indicate that the optical enantiomers of 13 obtained from HPLC exhibit promising chiroptical properties.
Two pairs of isomers of heptagon-embedded helical arenes (3/6 and 10/13) have been strategically prepared, where the molecular structures of 3 and 13 have been identified through single crystal X-ray diffraction analysis. The effect of the heptagon unit on the physical properties of 3, 6, 10, and 13 is investigated in a comparative manner, and the results indicate that the optical enantiomers of 13 obtained from HPLC exhibit promising chiroptical properties.
