Chirality-assisted synthesis (CAS) embodies a powerful strategy for the creation of chiral molecules with well-defined shapes and large cavities. In this communication, we show that C-shaped molecular receptors created with this approach bind to stacks of amphipathic perylenediimide (PDI) dyes. Evidence from 1H NMR titrations, DOSY-NMR studies, and all-atom molecular dynamics simulations indicates that – in the preferred supramolecular binding mode – such polyaromatic strips specifically recognize stacked PDI dimers in solution. These results represent a key step toward the controlled self-assembly of dye molecules inside chiral cavities of shape-persistent, polyaromatic strips.

- 9 Perylene-3,4,9,10-tetracarboxylic dianhydride (5, 0.05 g, 0.127 mmol), methoxypolyethylene glycol amine (6, M n = 1000 Da, 0.254 g, 0.254 mmol), and zinc acetate (0.0236 g, 0.127 mmol) were mixed with imidazole (2.0 g, 29.4 mmol) under a nitrogen atmosphere. The reaction mixture was heated for 24 h at 100–110 °C. After cooling to room temperature, 1 N HCl (15 mL) was added to protonate all of the imidazole, followed by stirring at room temperature for 1 h. The resulting solution was extracted with CH2Cl2 four times, and the organic layer was dried over anhydrous MgSO4, followed by evaporation of the solvent under reduced pressure. The crude product was purified by flash chromatography over silica gel (eluent: 1:9 v/v MeOH–CH2Cl2) to afford the dye 7 (75%) as a red solid. Characterization Data for 7 1H NMR (500 MHz, CDCl3): δ = 8.71 (d, J = 8.0 Hz, 4 H), 8.67 (d, J = 8.0 Hz, 4 H), 4.47 (t, J = 6.1 Hz, 4 H), 3.86 (t, J = 6.1 Hz, 4 H), 3.52–3.76 (m, 152 H), 3.38 (s, 6 H). 13C NMR (125 MHz, CDCl3): δ = 163.46, 134.70, 131.53, 129.46, 126.48, 123.33, 123.25, 72.07, 70.76, 70.75, 70.70 (br, multiple glycol peaks overlapping), 70.65, 68.02, 59.17, 39.43.

- 11a From the DOSY-1H NMR spectrum (Figure 4) of 7, the average diffusion constant for the protons attached to 7 was found to lie close to 1.5·10–10 m2 s–1. By applying the Stokes-Einstein equation11b this diffusion constant translates into a hydrodynamic radius of ca. 2.9 nm, assuming11c a viscosity of 0.5·10–2 Poise for the CD3CN–D2O (4:1 v/v) solvent mixture employed. This measured hydrodynamic radius is consistent with the predominant association of 7 into a dimeric, supramolecular complex 7@7.

- 14a In the DOSY-1H NMR spectrum recorded for the mixture of 4 and 7, the resonance e of 4 was not resolved, since the signal overlaps with the resonance of proton y on the dye 7. Note that such difficulties in resolving the diffusion constants of nearby DOSY-NMR signals often arise due to the nature of the inverse Laplace transform.
