    • Degradation of both dye moieties was observed at higher TFA concentrations (see Figure 11SI-13SI in the Supporting Information), whereby degradation of the acceptor was even faster than that of the donor. As a consequence of these findings, measurements of the fluorescence spectra in the titration experiments were performed as quickly as possible after mixing the cavitand with TFA (after ca. 20 s). Because slight degradation of the BODIPY-dye moieties could not be avoided, and because the acceptor dye degrades more quickly than the donor dye, the absolute FRET efficiencies for cavitands 1 - 4 are artificially low under these conditions. However, because a uniform experimental protocol was used throughout these measurements, the relative FRET efficiencies within the cavitand series are internally consistent.
