Abstract

On or off? A new excimer band at lambda = 570 nm was visualized during the noncovalent host-guest interaction between thioflavin T (ThT) and cucurbit[8]uril (CB8). Controlled dissociation of this assembly in the presence of Ca(2+) was demonstrated as an on/off fluorescence switch (see picture).
