Front Cover: Cooperativity in Hydrogen‐Bonded Macrocycles Derived from Nucleobases (Eur. J. Org. Chem. 19/2024).

The Front Cover of the European Journal of Organic Chemistry showcases a molecular model of a hydrogen-bonded quartet created through the stepwise addition of a supramolecular building block. The model demonstrates the hindrance of cooperative self-assembly in hydrogen-bonded macrocycles due to the electron abstracting capability of a rigid linear π-conjugated linker. The research article by P. Vermeeren, C. Fonseca Guerra, J. Poater, and their colleagues provides further details and can be accessed using the DOI: 10.1002/ejoc.202301164. The cover design was created by D. Almacellas. [Extracted from the article]
