Artifical Leaves …are an example of functional multicomponent architectures requiring three-dimensional organization for their creation. In their Communication on page 3727 ff., S. Matile et al. work toward this demanding objective, presenting interdigitating naphthalenediimide acceptors of different color and redox potential designed to zip up along interdigitating rigid-rod donors to produce supramolecular cascade n/p-heterojunctions on solid substrates.
