Aptly folded : Dynamic polymer libraries were generated by polycondensation through reversible imine bonds and can undergo driven evolution under the double stimuli of donor–acceptor stacking and metal‐ion binding (see picture). The specific binding modes of alkali metal ions are associated with specific constitutional changes and with different optical natures that reflect the presence and the positions of donor and acceptor units within the folded dynamer.
