Evaporation rate-based selection of supramolecular chiralityElectronic supplementary information (ESI) available: Experimental procedures and spectral data. See DOI: 10.1039/c6cc09842h

We demonstrate the evaporation rate-based selection of supramolecular chirality for the first time. P-type aggregates prepared by fast evaporation, and M-type aggregates prepared by slow evaporation are kinetic and thermodynamic products under dynamic reaction conditions, respectively. These findings provide a novel solution reaction chemistry under the dynamic reaction conditions. The supramolecular chirality of aggregates of π-conjugated polymers can be reversed by changing the evaporation rate.
