Lemniscular carbon nanohoops with contiguous conjugation from planar chiral [2.2]paracyclophane: influence of the regioselective synthesis on topological chirality

Abstract

We report herein two lemniscular carbon nanohoops bis-po-CC and bis-pm-TC with contiguous conjugation from planar chiral [2.2]paracyclophane, and elucidate the influence of the regioselective synthesis on their topological chirality.
