Front Cover: A Phenyl‐Ethynyl‐Macrocycle: A Model Compound for “Geländer” Oligomers Comprising Reactive Conjugated Banisters (Eur. J. Org. Chem. 26/2018)

Abstract

The Front Cover shows two macrocycles, one representing the smallest member of a series of “Geländer” oligomers with a conjugated banister comprising exclusively sp2‐ and sp‐hybridized carbon atoms, and the Huisgen's (2+3) cycloaddition analogue. Both molecules are surrounded by a water slide, representing the helicity of the two macrocycles. The banister of the diethynyl macrocycle shows a continuous helicity, whereas the banister of the cycloaddition product is distorted.
