Abstract
J-aggregates are supramolecular structures with great potential as building blocks made of organic materials for subwavelength confinement. Their extraordinary properties are related to the delocalisation of excitons between the monomers. It is possible to modify the arrangements of monomers by hydrodynamic forces obtaining a strong circular dichroism signal. In this work, we study how to tune this induced circular dichroism response as a function of the stirring velocity and the ionic strength of the dispersion media for a large variety of J-aggregates. The final aim of this work is to reflect the potential use of this chiral J-aggregates as building blocks for fluorescent tunable chiral-nanoprobes.
