Graphical Abstract
Figure 1: Molecular structures of ligands 1, 2, 3, and 4 and of the resulting products, i.e., rectangle 5, sa...
Scheme 1: Guest addition/removal and reversible interconversion between supramolecular architectures.
Scheme 2: Completive and incomplete self-sorting in presence of copper(I) and rhodium complex 3.
Figure 2: Comparison of partial 1H NMR spectra (400 MHz, CD2Cl2, 298 K) of (a) ligand 2; (b) ligand 1; (c) po...
Figure 3: (a) UV–vis titration of rectangle 5 (2.98 μM) with DABCO (4); (b) several reversible cycles of inte...
Scheme 3: The high selectivity for DABCO in the transformation.
Figure 4: Partial spectra (400 MHz, CD2Cl2, 298 K) showing the reversible switching between rectangle and san...
