The selectively functionalized nanometric knotane platform can be compared with a metal ion capable of coordinating three ligands. In their Full Paper on page 5685 ff., V. Balzani, F. Vögtle, O. Lukin et al. describe this concept with respect to an amideknotane substituted with fluorescent dansyl and/or pyrenesulfonyl moieties. UV/Vis absorption spectra, emission spectra, and the emission lifetimes of the fluorescent knotanes were investigated.
