Fluorescent chirality recognition by simple boronate ensembles with aggregation-induced emission capability.

Chiral ensembles were spontaneously formed in solution through boronate esterification of structurally defined di(boronic acid)-appended tetraphenylethylene (DB-TPE) and commercially available l- or d-tartaric acid, showing enantioselective aggregation behavior for chiral diamines as well as cinchona alkaloids enabling the fluorescent recognition of their chirality.
