        abstract = {This work sheds new light on the stereoselective synthesis of chiral macrocycles containing twisted aromatic units, valuable {\ensuremath{\pi}}-conjugated materials for recognition, sensing, and optoelectronics. For the first time, we use the Curtin-Hammett principle to investigate a chiral macrocyclisation reaction, revealing the potential for supramolecular {\ensuremath{\pi}}-{\ensuremath{\pi}} interactions to direct the outcome of a dynamic kinetic resolution, favouring the opposite macrocyclic product to that expected under reversible, thermodynamically controlled conditions. Specifically, a dynamic, racemic perylene diimide dye (1 : 1 P : M) is strapped with an enantiopure (S)-1,1?-bi-2-naphthol group (P-BINOL) to form two diastereomeric macrocyclic products, the homochiral macrocycle (PP) and the heterochiral species (PM). We find there is notable selectivity for the PM macrocycle (dr = 4 : 1), which is rationalised by kinetic templation from intramolecular aromatic non-covalent interactions between the P-BINOL {\ensuremath{\pi}}-donor and the M-PDI {\ensuremath{\pi}}-acceptor during the macrocyclisation reaction.},
