title: Fluorescent H-Aggregates Hosted by a Charged Cyclodextrin Cavity.
abstract: Most macrocyclic host molecules, including cyclodextrins, usually prevent self-aggregation of the guest organic molecules, by exploiting inclusion complexation of the guest with the host. In this work, it was found that a negatively charged β-cylcodextrin derivative induces aggregation of a well-known amyloid sensing dye, Thioflavin-T, and leads to an unprecedented formation of the rarely observed emissive H-type aggregates of the dye.
