Graphical Abstract
In the twist: The extent of twisting from planarity in a series of perylenetetracarboxylic diimides (PDIs) modulates the attractive π–π stacking force, revealing an array of inherent molecular recognition codes. Such coded self-assembly directs specific reaction pathways so that a mixture of reactive monomers with different codes results in identical products as when the reactions were carried out in separate flasks (see picture).
