Multicomponent pseudorotaxane superarchitectures are generated when a tetracationic filament, bearing dialkyl ammonium (NH2+) and 4,4′-bipyridinium (bpym2+) recognition sites, self-assembles selectively with various crown ethers, such as dicyclohexyl[24]crown-8 (Dcy24C8) and 2,3- dinaptho[30]crown-10 (2/3DN30C10) [see figure]. The selective self-processes were utilized for the development of pH-controlled supramolecular switches.
