Cover Feature: Bridging and Conformational Control of Porphyrin Units through Non‐Traditional Rigid Scaffolds (Chem. Eur. J. 11/2020)

Electronically isolating bicyclo[1.1.1]pentane (BCP) or cubane units were combined with porphyrin units to access rigid scaffold derivatives such as porphyrin—cubane–porphyrin and porphyrin—BCP–porphyrin arrays. The reaction conditions tolerate a variety of substituents and generate dyads with varying lengths and angles and fascinating supramolecular architectures. The cover art by Ella Marushchenko illustrates how the two porphyrin units are tacked together with stapler BCP units in a rigid linear manner. More information can be found in the Full Paper by M. O. Senge et al. on page 2405.
