Vortexes and Nanoscale Chirality

Vortexes and Nanoscale Chirality

J‐aggregates respond dynamically to vortexes created by stirring. The CD signal inverts with stirring sense and its intensity increases. Prolonged stirring leads to deposition of chiral aggregates on the cuvette wall, the chirality of the deposits depends on the stirring sense. Stirring shifts the e...

description J‐aggregates respond dynamically to vortexes created by stirring. The CD signal inverts with stirring sense and its intensity increases. Prolonged stirring leads to deposition of chiral aggregates on the cuvette wall, the chirality of the deposits depends on the stirring sense. Stirring shifts the equilibrium of a racemic mixture towards the side chosen (and favored) by the stirring sense (see picture, CW=clockwise, CCW=counter clockwise stirring).
