Abstract

Abstract : Unprecedented high molar circular dichroism values for all‐carbon macrocycles were revealed in 1, 3‐butadiyne bridged pseudo‐ meta‐ [2.2]paracyclophanes. The angle and flexibility of the pseudo‐ meta substituents enabled high yielding macrocyclization reactions, and the studied trimeric, tetrameric, pentameric and hexameric structures further displayed astonishing through‐space polymer‐like conjugation lengths.
