Developing chiral aggregates exhibiting anti-S-shaped CD-ee dependence: using a meso-isomer to tune dynamic aggregates induced by enantiomers†

Abstract

We report the use of the meso-isomer of tartaric acid, meso-tartaric acid, to tune the chirality of the dynamic aggregates of a perylenebisimide dye bearing boronic acid groups in the presence of enantiomeric l-/d-tartaric acid. The CD-ee dependence changes from S- to anti-S-shaped. A change in the structures of the chiral aggregates led by the meso-tartaric acid is identified.
