Aggregates of perylene diimides are prized for their stability, efficiency and versatility in a range of optoelectronic applications. Structural control can be achieved via the supramolecular polymerization of perylene diimides, where the morphology and function of aggregates is modulated by rational design of the perylene diimide monomers. This review examines how chemical substitution at the imide position of perylene diimides (which does not affect the parent chromophore's electronic structure) can be used to tune the morphology, H‐ or J‐ aggregation and mode of growth of perylene diimide supramolecular polymers. It also appraises the current state of the art for controlling the degree of aggregation in isodesmic, cooperative and anti‐cooperative systems, and pinpoints the most promising routes and future challenges to achieving greater morphological control of these supramolecular constructs.
